Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637078, here are decompositions:

11 + 8637067 = 8637078
17 + 8637061 = 8637078
19 + 8637059 = 8637078
61 + 8637017 = 8637078
71 + 8637007 = 8637078
89 + 8636989 = 8637078
157 + 8636921 = 8637078
167 + 8636911 = 8637078

Showing the first eight; more decompositions exist.
