Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671588, here are decompositions:

5 + 8671583 = 8671588
71 + 8671517 = 8671588
89 + 8671499 = 8671588
131 + 8671457 = 8671588
179 + 8671409 = 8671588
227 + 8671361 = 8671588
257 + 8671331 = 8671588
281 + 8671307 = 8671588

Showing the first eight; more decompositions exist.
