Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77512, here are decompositions:

3 + 77509 = 77512
23 + 77489 = 77512
41 + 77471 = 77512
173 + 77339 = 77512
233 + 77279 = 77512
251 + 77261 = 77512
263 + 77249 = 77512
269 + 77243 = 77512

Showing the first eight; more decompositions exist.
