Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726786, here are decompositions:

73 + 8726713 = 8726786
109 + 8726677 = 8726786
139 + 8726647 = 8726786
199 + 8726587 = 8726786
307 + 8726479 = 8726786
337 + 8726449 = 8726786
457 + 8726329 = 8726786
463 + 8726323 = 8726786

Showing the first eight; more decompositions exist.
