Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637486, here are decompositions:

5 + 8637481 = 8637486
19 + 8637467 = 8637486
37 + 8637449 = 8637486
59 + 8637427 = 8637486
107 + 8637379 = 8637486
113 + 8637373 = 8637486
149 + 8637337 = 8637486
163 + 8637323 = 8637486

Showing the first eight; more decompositions exist.
