Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637564, here are decompositions:

37 + 8637527 = 8637564
41 + 8637523 = 8637564
43 + 8637521 = 8637564
71 + 8637493 = 8637564
73 + 8637491 = 8637564
83 + 8637481 = 8637564
97 + 8637467 = 8637564
113 + 8637451 = 8637564

Showing the first eight; more decompositions exist.
