Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601212, here are decompositions:

3 + 8601209 = 8601212
43 + 8601169 = 8601212
199 + 8601013 = 8601212
241 + 8600971 = 8601212
271 + 8600941 = 8601212
313 + 8600899 = 8601212
331 + 8600881 = 8601212
619 + 8600593 = 8601212

Showing the first eight; more decompositions exist.
