Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637624, here are decompositions:

5 + 8637619 = 8637624
7 + 8637617 = 8637624
13 + 8637611 = 8637624
97 + 8637527 = 8637624
101 + 8637523 = 8637624
103 + 8637521 = 8637624
131 + 8637493 = 8637624
157 + 8637467 = 8637624

Showing the first eight; more decompositions exist.
