Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651672, here are decompositions:

229 + 8651443 = 8651672
283 + 8651389 = 8651672
313 + 8651359 = 8651672
349 + 8651323 = 8651672
433 + 8651239 = 8651672
439 + 8651233 = 8651672
691 + 8650981 = 8651672
823 + 8650849 = 8651672

Showing the first eight; more decompositions exist.
