Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672748, here are decompositions:

17 + 8672731 = 8672748
41 + 8672707 = 8672748
61 + 8672687 = 8672748
89 + 8672659 = 8672748
101 + 8672647 = 8672748
107 + 8672641 = 8672748
109 + 8672639 = 8672748
127 + 8672621 = 8672748

Showing the first eight; more decompositions exist.
