Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756668, here are decompositions:

59 + 8756609 = 8756668
101 + 8756567 = 8756668
149 + 8756519 = 8756668
197 + 8756471 = 8756668
227 + 8756441 = 8756668
311 + 8756357 = 8756668
467 + 8756201 = 8756668
509 + 8756159 = 8756668

Showing the first eight; more decompositions exist.
