Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632218, here are decompositions:

31 + 8632187 = 8632218
61 + 8632157 = 8632218
79 + 8632139 = 8632218
131 + 8632087 = 8632218
137 + 8632081 = 8632218
149 + 8632069 = 8632218
191 + 8632027 = 8632218
239 + 8631979 = 8632218

Showing the first eight; more decompositions exist.
