Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612972, here are decompositions:

3 + 8612969 = 8612972
13 + 8612959 = 8612972
31 + 8612941 = 8612972
79 + 8612893 = 8612972
229 + 8612743 = 8612972
241 + 8612731 = 8612972
271 + 8612701 = 8612972
283 + 8612689 = 8612972

Showing the first eight; more decompositions exist.
