Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672658, here are decompositions:

11 + 8672647 = 8672658
17 + 8672641 = 8672658
19 + 8672639 = 8672658
37 + 8672621 = 8672658
61 + 8672597 = 8672658
97 + 8672561 = 8672658
107 + 8672551 = 8672658
131 + 8672527 = 8672658

Showing the first eight; more decompositions exist.
