Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756628, here are decompositions:

5 + 8756623 = 8756628
19 + 8756609 = 8756628
37 + 8756591 = 8756628
61 + 8756567 = 8756628
71 + 8756557 = 8756628
109 + 8756519 = 8756628
157 + 8756471 = 8756628
191 + 8756437 = 8756628

Showing the first eight; more decompositions exist.
