Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702628, here are decompositions:

31 + 8702597 = 8702628
37 + 8702591 = 8702628
41 + 8702587 = 8702628
59 + 8702569 = 8702628
71 + 8702557 = 8702628
89 + 8702539 = 8702628
131 + 8702497 = 8702628
139 + 8702489 = 8702628

Showing the first eight; more decompositions exist.
