Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621404, here are decompositions:

167 + 8621237 = 8621404
191 + 8621213 = 8621404
251 + 8621153 = 8621404
257 + 8621147 = 8621404
317 + 8621087 = 8621404
353 + 8621051 = 8621404
431 + 8620973 = 8621404
461 + 8620943 = 8621404

Showing the first eight; more decompositions exist.
