Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651612, here are decompositions:

3 + 8651609 = 8651612
31 + 8651581 = 8651612
223 + 8651389 = 8651612
283 + 8651329 = 8651612
331 + 8651281 = 8651612
373 + 8651239 = 8651612
379 + 8651233 = 8651612
421 + 8651191 = 8651612

Showing the first eight; more decompositions exist.
