Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638364, here are decompositions:

37 + 8638327 = 8638364
73 + 8638291 = 8638364
127 + 8638237 = 8638364
151 + 8638213 = 8638364
157 + 8638207 = 8638364
181 + 8638183 = 8638364
313 + 8638051 = 8638364
331 + 8638033 = 8638364

Showing the first eight; more decompositions exist.
