Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670650, here are decompositions:

13 + 8670637 = 8670650
31 + 8670619 = 8670650
61 + 8670589 = 8670650
67 + 8670583 = 8670650
97 + 8670553 = 8670650
127 + 8670523 = 8670650
151 + 8670499 = 8670650
199 + 8670451 = 8670650

Showing the first eight; more decompositions exist.
