Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752512, here are decompositions:

5 + 8752507 = 8752512
71 + 8752441 = 8752512
151 + 8752361 = 8752512
173 + 8752339 = 8752512
191 + 8752321 = 8752512
239 + 8752273 = 8752512
281 + 8752231 = 8752512
311 + 8752201 = 8752512

Showing the first eight; more decompositions exist.
