Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743656, here are decompositions:

17 + 8743639 = 8743656
23 + 8743633 = 8743656
59 + 8743597 = 8743656
67 + 8743589 = 8743656
73 + 8743583 = 8743656
107 + 8743549 = 8743656
109 + 8743547 = 8743656
157 + 8743499 = 8743656

Showing the first eight; more decompositions exist.
