Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757784, here are decompositions:

71 + 8757713 = 8757784
83 + 8757701 = 8757784
257 + 8757527 = 8757784
311 + 8757473 = 8757784
443 + 8757341 = 8757784
521 + 8757263 = 8757784
593 + 8757191 = 8757784
641 + 8757143 = 8757784

Showing the first eight; more decompositions exist.
