Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637588, here are decompositions:

61 + 8637527 = 8637588
67 + 8637521 = 8637588
79 + 8637509 = 8637588
97 + 8637491 = 8637588
107 + 8637481 = 8637588
137 + 8637451 = 8637588
139 + 8637449 = 8637588
251 + 8637337 = 8637588

Showing the first eight; more decompositions exist.
