Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725650, here are decompositions:

7 + 8725643 = 8725650
19 + 8725631 = 8725650
23 + 8725627 = 8725650
29 + 8725621 = 8725650
41 + 8725609 = 8725650
79 + 8725571 = 8725650
83 + 8725567 = 8725650
103 + 8725547 = 8725650

Showing the first eight; more decompositions exist.
