Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637580, here are decompositions:

53 + 8637527 = 8637580
59 + 8637521 = 8637580
71 + 8637509 = 8637580
89 + 8637491 = 8637580
113 + 8637467 = 8637580
131 + 8637449 = 8637580
239 + 8637341 = 8637580
257 + 8637323 = 8637580

Showing the first eight; more decompositions exist.
