Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637586, here are decompositions:

59 + 8637527 = 8637586
137 + 8637449 = 8637586
263 + 8637323 = 8637586
359 + 8637227 = 8637586
383 + 8637203 = 8637586
467 + 8637119 = 8637586
479 + 8637107 = 8637586
569 + 8637017 = 8637586

Showing the first eight; more decompositions exist.
