Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675778, here are decompositions:

11 + 8675767 = 8675778
29 + 8675749 = 8675778
79 + 8675699 = 8675778
101 + 8675677 = 8675778
107 + 8675671 = 8675778
127 + 8675651 = 8675778
157 + 8675621 = 8675778
257 + 8675521 = 8675778

Showing the first eight; more decompositions exist.
