Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749656, here are decompositions:

5 + 8749651 = 8749656
29 + 8749627 = 8749656
43 + 8749613 = 8749656
53 + 8749603 = 8749656
67 + 8749589 = 8749656
107 + 8749549 = 8749656
199 + 8749457 = 8749656
233 + 8749423 = 8749656

Showing the first eight; more decompositions exist.
