Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725228, here are decompositions:

11 + 8725217 = 8725228
89 + 8725139 = 8725228
137 + 8725091 = 8725228
191 + 8725037 = 8725228
401 + 8724827 = 8725228
509 + 8724719 = 8725228
587 + 8724641 = 8725228
761 + 8724467 = 8725228

Showing the first eight; more decompositions exist.
