Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627528, here are decompositions:

31 + 8627497 = 8627528
61 + 8627467 = 8627528
97 + 8627431 = 8627528
157 + 8627371 = 8627528
199 + 8627329 = 8627528
229 + 8627299 = 8627528
271 + 8627257 = 8627528
277 + 8627251 = 8627528

Showing the first eight; more decompositions exist.
