Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742972, here are decompositions:

31 + 8742941 = 8742972
41 + 8742931 = 8742972
53 + 8742919 = 8742972
151 + 8742821 = 8742972
193 + 8742779 = 8742972
233 + 8742739 = 8742972
283 + 8742689 = 8742972
349 + 8742623 = 8742972

Showing the first eight; more decompositions exist.
