Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756530, here are decompositions:

11 + 8756519 = 8756530
23 + 8756507 = 8756530
59 + 8756471 = 8756530
71 + 8756459 = 8756530
89 + 8756441 = 8756530
137 + 8756393 = 8756530
149 + 8756381 = 8756530
173 + 8756357 = 8756530

Showing the first eight; more decompositions exist.
