Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672672, here are decompositions:

13 + 8672659 = 8672672
31 + 8672641 = 8672672
109 + 8672563 = 8672672
163 + 8672509 = 8672672
409 + 8672263 = 8672672
433 + 8672239 = 8672672
571 + 8672101 = 8672672
691 + 8671981 = 8672672

Showing the first eight; more decompositions exist.
