Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651412, here are decompositions:

13 + 8651399 = 8651412
23 + 8651389 = 8651412
53 + 8651359 = 8651412
59 + 8651353 = 8651412
83 + 8651329 = 8651412
89 + 8651323 = 8651412
101 + 8651311 = 8651412
131 + 8651281 = 8651412

Showing the first eight; more decompositions exist.
