Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671486, here are decompositions:

17 + 8671469 = 8671486
23 + 8671463 = 8671486
29 + 8671457 = 8671486
59 + 8671427 = 8671486
179 + 8671307 = 8671486
293 + 8671193 = 8671486
353 + 8671133 = 8671486
359 + 8671127 = 8671486

Showing the first eight; more decompositions exist.
