Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628650, here are decompositions:

3 + 8628647 = 8628650
7 + 8628643 = 8628650
97 + 8628553 = 8628650
103 + 8628547 = 8628650
157 + 8628493 = 8628650
229 + 8628421 = 8628650
379 + 8628271 = 8628650
463 + 8628187 = 8628650

Showing the first eight; more decompositions exist.
