Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742938, here are decompositions:

7 + 8742931 = 8742938
19 + 8742919 = 8742938
151 + 8742787 = 8742938
199 + 8742739 = 8742938
367 + 8742571 = 8742938
397 + 8742541 = 8742938
409 + 8742529 = 8742938
439 + 8742499 = 8742938

Showing the first eight; more decompositions exist.
