Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637558, here are decompositions:

31 + 8637527 = 8637558
37 + 8637521 = 8637558
67 + 8637491 = 8637558
107 + 8637451 = 8637558
109 + 8637449 = 8637558
131 + 8637427 = 8637558
179 + 8637379 = 8637558
239 + 8637319 = 8637558

Showing the first eight; more decompositions exist.
