Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640502, here are decompositions:

83 + 8640419 = 8640502
173 + 8640329 = 8640502
239 + 8640263 = 8640502
251 + 8640251 = 8640502
281 + 8640221 = 8640502
443 + 8640059 = 8640502
593 + 8639909 = 8640502
599 + 8639903 = 8640502

Showing the first eight; more decompositions exist.
