Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651238, here are decompositions:

5 + 8651233 = 8651238
7 + 8651231 = 8651238
31 + 8651207 = 8651238
47 + 8651191 = 8651238
59 + 8651179 = 8651238
97 + 8651141 = 8651238
191 + 8651047 = 8651238
199 + 8651039 = 8651238

Showing the first eight; more decompositions exist.
