Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637528, here are decompositions:

5 + 8637523 = 8637528
7 + 8637521 = 8637528
19 + 8637509 = 8637528
37 + 8637491 = 8637528
47 + 8637481 = 8637528
61 + 8637467 = 8637528
79 + 8637449 = 8637528
101 + 8637427 = 8637528

Showing the first eight; more decompositions exist.
