Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651212, here are decompositions:

5 + 8651207 = 8651212
23 + 8651189 = 8651212
71 + 8651141 = 8651212
149 + 8651063 = 8651212
173 + 8651039 = 8651212
233 + 8650979 = 8651212
293 + 8650919 = 8651212
419 + 8650793 = 8651212

Showing the first eight; more decompositions exist.
