Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756690, here are decompositions:

3 + 8756687 = 8756690
13 + 8756677 = 8756690
31 + 8756659 = 8756690
37 + 8756653 = 8756690
67 + 8756623 = 8756690
97 + 8756593 = 8756690
139 + 8756551 = 8756690
157 + 8756533 = 8756690

Showing the first eight; more decompositions exist.
