Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672650, here are decompositions:

3 + 8672647 = 8672650
11 + 8672639 = 8672650
29 + 8672621 = 8672650
53 + 8672597 = 8672650
89 + 8672561 = 8672650
131 + 8672519 = 8672650
137 + 8672513 = 8672650
149 + 8672501 = 8672650

Showing the first eight; more decompositions exist.
