The grid shows a cross-figure with two digits given as a start. All 11 two- and three-digit answers are prime and none has a leading zero; no digit appears more than once in any row, column or either of the two long diagonals; no even digit appears more than once anywhere.
What are the numbers in the shaded regions?
This puzzle is similar to Enigma 1740 and Enigma 1730 (both also set by Peter Chamberlain).
