Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612664, here are decompositions:

7 + 8612657 = 8612664
23 + 8612641 = 8612664
31 + 8612633 = 8612664
37 + 8612627 = 8612664
83 + 8612581 = 8612664
167 + 8612497 = 8612664
191 + 8612473 = 8612664
227 + 8612437 = 8612664

Showing the first eight; more decompositions exist.
