Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621410, here are decompositions:

71 + 8621339 = 8621410
101 + 8621309 = 8621410
167 + 8621243 = 8621410
173 + 8621237 = 8621410
197 + 8621213 = 8621410
227 + 8621183 = 8621410
257 + 8621153 = 8621410
263 + 8621147 = 8621410

Showing the first eight; more decompositions exist.
