Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724650, here are decompositions:

7 + 8724643 = 8724650
19 + 8724631 = 8724650
31 + 8724619 = 8724650
61 + 8724589 = 8724650
139 + 8724511 = 8724650
157 + 8724493 = 8724650
163 + 8724487 = 8724650
229 + 8724421 = 8724650

Showing the first eight; more decompositions exist.
