Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637648, here are decompositions:

7 + 8637641 = 8637648
11 + 8637637 = 8637648
29 + 8637619 = 8637648
31 + 8637617 = 8637648
37 + 8637611 = 8637648
127 + 8637521 = 8637648
139 + 8637509 = 8637648
157 + 8637491 = 8637648

Showing the first eight; more decompositions exist.
