Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672728, here are decompositions:

5 + 8672723 = 8672728
41 + 8672687 = 8672728
89 + 8672639 = 8672728
107 + 8672621 = 8672728
131 + 8672597 = 8672728
167 + 8672561 = 8672728
227 + 8672501 = 8672728
257 + 8672471 = 8672728

Showing the first eight; more decompositions exist.
