Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738786, here are decompositions:

3 + 8738783 = 8738786
19 + 8738767 = 8738786
73 + 8738713 = 8738786
79 + 8738707 = 8738786
127 + 8738659 = 8738786
313 + 8738473 = 8738786
337 + 8738449 = 8738786
349 + 8738437 = 8738786

Showing the first eight; more decompositions exist.
