Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648422, here are decompositions:

53 + 8648369 = 8648422
89 + 8648333 = 8648422
311 + 8648111 = 8648422
389 + 8648033 = 8648422
443 + 8647979 = 8648422
509 + 8647913 = 8648422
599 + 8647823 = 8648422
683 + 8647739 = 8648422

Showing the first eight; more decompositions exist.
