Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637630, here are decompositions:

11 + 8637619 = 8637630
13 + 8637617 = 8637630
19 + 8637611 = 8637630
103 + 8637527 = 8637630
107 + 8637523 = 8637630
109 + 8637521 = 8637630
137 + 8637493 = 8637630
139 + 8637491 = 8637630

Showing the first eight; more decompositions exist.
