Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701618, here are decompositions:

41 + 8701577 = 8701618
47 + 8701571 = 8701618
59 + 8701559 = 8701618
89 + 8701529 = 8701618
227 + 8701391 = 8701618
251 + 8701367 = 8701618
269 + 8701349 = 8701618
347 + 8701271 = 8701618

Showing the first eight; more decompositions exist.
