Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651290, here are decompositions:

23 + 8651267 = 8651290
29 + 8651261 = 8651290
59 + 8651231 = 8651290
83 + 8651207 = 8651290
101 + 8651189 = 8651290
149 + 8651141 = 8651290
173 + 8651117 = 8651290
227 + 8651063 = 8651290

Showing the first eight; more decompositions exist.
