Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759778, here are decompositions:

7 + 8759771 = 8759778
17 + 8759761 = 8759778
19 + 8759759 = 8759778
29 + 8759749 = 8759778
47 + 8759731 = 8759778
89 + 8759689 = 8759778
101 + 8759677 = 8759778
197 + 8759581 = 8759778

Showing the first eight; more decompositions exist.
