Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671624, here are decompositions:

41 + 8671583 = 8671624
107 + 8671517 = 8671624
113 + 8671511 = 8671624
167 + 8671457 = 8671624
197 + 8671427 = 8671624
257 + 8671367 = 8671624
263 + 8671361 = 8671624
293 + 8671331 = 8671624

Showing the first eight; more decompositions exist.
