Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672724, here are decompositions:

17 + 8672707 = 8672724
37 + 8672687 = 8672724
83 + 8672641 = 8672724
103 + 8672621 = 8672724
127 + 8672597 = 8672724
163 + 8672561 = 8672724
173 + 8672551 = 8672724
197 + 8672527 = 8672724

Showing the first eight; more decompositions exist.
