Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701666, here are decompositions:

23 + 8701643 = 8701666
89 + 8701577 = 8701666
107 + 8701559 = 8701666
137 + 8701529 = 8701666
167 + 8701499 = 8701666
173 + 8701493 = 8701666
257 + 8701409 = 8701666
263 + 8701403 = 8701666

Showing the first eight; more decompositions exist.
