Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700130, here are decompositions:

17 + 8700113 = 8700130
59 + 8700071 = 8700130
71 + 8700059 = 8700130
83 + 8700047 = 8700130
137 + 8699993 = 8700130
149 + 8699981 = 8700130
251 + 8699879 = 8700130
317 + 8699813 = 8700130

Showing the first eight; more decompositions exist.
