Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704864, here are decompositions:

11 + 8704853 = 8704864
53 + 8704811 = 8704864
107 + 8704757 = 8704864
173 + 8704691 = 8704864
251 + 8704613 = 8704864
257 + 8704607 = 8704864
263 + 8704601 = 8704864
317 + 8704547 = 8704864

Showing the first eight; more decompositions exist.
