Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671564, here are decompositions:

47 + 8671517 = 8671564
53 + 8671511 = 8671564
101 + 8671463 = 8671564
107 + 8671457 = 8671564
137 + 8671427 = 8671564
197 + 8671367 = 8671564
233 + 8671331 = 8671564
257 + 8671307 = 8671564

Showing the first eight; more decompositions exist.
