Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671642, here are decompositions:

3 + 8671639 = 8671642
11 + 8671631 = 8671642
53 + 8671589 = 8671642
59 + 8671583 = 8671642
131 + 8671511 = 8671642
173 + 8671469 = 8671642
179 + 8671463 = 8671642
233 + 8671409 = 8671642

Showing the first eight; more decompositions exist.
