Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742962, here are decompositions:

31 + 8742931 = 8742962
43 + 8742919 = 8742962
223 + 8742739 = 8742962
421 + 8742541 = 8742962
433 + 8742529 = 8742962
463 + 8742499 = 8742962
499 + 8742463 = 8742962
541 + 8742421 = 8742962

Showing the first eight; more decompositions exist.
