Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649580, here are decompositions:

47 + 8649533 = 8649580
59 + 8649521 = 8649580
89 + 8649491 = 8649580
101 + 8649479 = 8649580
113 + 8649467 = 8649580
197 + 8649383 = 8649580
227 + 8649353 = 8649580
257 + 8649323 = 8649580

Showing the first eight; more decompositions exist.
