Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711778, here are decompositions:

11 + 8711767 = 8711778
29 + 8711749 = 8711778
37 + 8711741 = 8711778
41 + 8711737 = 8711778
59 + 8711719 = 8711778
71 + 8711707 = 8711778
109 + 8711669 = 8711778
151 + 8711627 = 8711778

Showing the first eight; more decompositions exist.
