Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637488, here are decompositions:

7 + 8637481 = 8637488
37 + 8637451 = 8637488
61 + 8637427 = 8637488
109 + 8637379 = 8637488
151 + 8637337 = 8637488
199 + 8637289 = 8637488
241 + 8637247 = 8637488
337 + 8637151 = 8637488

Showing the first eight; more decompositions exist.
