Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707512, here are decompositions:

83 + 8707429 = 8707512
179 + 8707333 = 8707512
223 + 8707289 = 8707512
239 + 8707273 = 8707512
271 + 8707241 = 8707512
293 + 8707219 = 8707512
353 + 8707159 = 8707512
389 + 8707123 = 8707512

Showing the first eight; more decompositions exist.
