Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756780, here are decompositions:

73 + 8756707 = 8756780
103 + 8756677 = 8756780
127 + 8756653 = 8756780
157 + 8756623 = 8756780
223 + 8756557 = 8756780
229 + 8756551 = 8756780
271 + 8756509 = 8756780
367 + 8756413 = 8756780

Showing the first eight; more decompositions exist.
