Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701672, here are decompositions:

29 + 8701643 = 8701672
41 + 8701631 = 8701672
101 + 8701571 = 8701672
113 + 8701559 = 8701672
173 + 8701499 = 8701672
179 + 8701493 = 8701672
263 + 8701409 = 8701672
269 + 8701403 = 8701672

Showing the first eight; more decompositions exist.
