Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637626, here are decompositions:

7 + 8637619 = 8637626
103 + 8637523 = 8637626
199 + 8637427 = 8637626
307 + 8637319 = 8637626
337 + 8637289 = 8637626
373 + 8637253 = 8637626
379 + 8637247 = 8637626
463 + 8637163 = 8637626

Showing the first eight; more decompositions exist.
