Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671636, here are decompositions:

3 + 8671633 = 8671636
5 + 8671631 = 8671636
47 + 8671589 = 8671636
53 + 8671583 = 8671636
137 + 8671499 = 8671636
167 + 8671469 = 8671636
173 + 8671463 = 8671636
179 + 8671457 = 8671636

Showing the first eight; more decompositions exist.
