Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671650, here are decompositions:

11 + 8671639 = 8671650
17 + 8671633 = 8671650
19 + 8671631 = 8671650
61 + 8671589 = 8671650
67 + 8671583 = 8671650
101 + 8671549 = 8671650
131 + 8671519 = 8671650
139 + 8671511 = 8671650

Showing the first eight; more decompositions exist.
