Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671684, here are decompositions:

53 + 8671631 = 8671684
101 + 8671583 = 8671684
167 + 8671517 = 8671684
173 + 8671511 = 8671684
227 + 8671457 = 8671684
257 + 8671427 = 8671684
317 + 8671367 = 8671684
353 + 8671331 = 8671684

Showing the first eight; more decompositions exist.
