Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651086, here are decompositions:

23 + 8651063 = 8651086
47 + 8651039 = 8651086
89 + 8650997 = 8651086
107 + 8650979 = 8651086
167 + 8650919 = 8651086
293 + 8650793 = 8651086
359 + 8650727 = 8651086
383 + 8650703 = 8651086

Showing the first eight; more decompositions exist.
