Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685528, here are decompositions:

11 + 8685517 = 8685528
149 + 8685379 = 8685528
151 + 8685377 = 8685528
157 + 8685371 = 8685528
239 + 8685289 = 8685528
277 + 8685251 = 8685528
317 + 8685211 = 8685528
331 + 8685197 = 8685528

Showing the first eight; more decompositions exist.
