Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706512, here are decompositions:

109 + 8706403 = 8706512
151 + 8706361 = 8706512
163 + 8706349 = 8706512
223 + 8706289 = 8706512
229 + 8706283 = 8706512
271 + 8706241 = 8706512
349 + 8706163 = 8706512
433 + 8706079 = 8706512

Showing the first eight; more decompositions exist.
