Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706528, here are decompositions:

31 + 8706497 = 8706528
67 + 8706461 = 8706528
71 + 8706457 = 8706528
109 + 8706419 = 8706528
151 + 8706377 = 8706528
167 + 8706361 = 8706528
179 + 8706349 = 8706528
191 + 8706337 = 8706528

Showing the first eight; more decompositions exist.
