Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756520, here are decompositions:

11 + 8756509 = 8756520
13 + 8756507 = 8756520
61 + 8756459 = 8756520
79 + 8756441 = 8756520
83 + 8756437 = 8756520
107 + 8756413 = 8756520
127 + 8756393 = 8756520
139 + 8756381 = 8756520

Showing the first eight; more decompositions exist.
