Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651194, here are decompositions:

3 + 8651191 = 8651194
5 + 8651189 = 8651194
53 + 8651141 = 8651194
131 + 8651063 = 8651194
197 + 8650997 = 8651194
401 + 8650793 = 8651194
467 + 8650727 = 8651194
491 + 8650703 = 8651194

Showing the first eight; more decompositions exist.
