Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704870, here are decompositions:

17 + 8704853 = 8704870
59 + 8704811 = 8704870
113 + 8704757 = 8704870
149 + 8704721 = 8704870
179 + 8704691 = 8704870
257 + 8704613 = 8704870
263 + 8704607 = 8704870
269 + 8704601 = 8704870

Showing the first eight; more decompositions exist.
