Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640652, here are decompositions:

149 + 8640503 = 8640652
233 + 8640419 = 8640652
389 + 8640263 = 8640652
401 + 8640251 = 8640652
431 + 8640221 = 8640652
491 + 8640161 = 8640652
593 + 8640059 = 8640652
701 + 8639951 = 8640652

Showing the first eight; more decompositions exist.
