Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640550, here are decompositions:

3 + 8640547 = 8640550
47 + 8640503 = 8640550
131 + 8640419 = 8640550
263 + 8640287 = 8640550
353 + 8640197 = 8640550
389 + 8640161 = 8640550
491 + 8640059 = 8640550
563 + 8639987 = 8640550

Showing the first eight; more decompositions exist.
