Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651122, here are decompositions:

3 + 8651119 = 8651122
5 + 8651117 = 8651122
59 + 8651063 = 8651122
71 + 8651051 = 8651122
83 + 8651039 = 8651122
113 + 8651009 = 8651122
401 + 8650721 = 8651122
419 + 8650703 = 8651122

Showing the first eight; more decompositions exist.
