Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728964, here are decompositions:

37 + 8728927 = 8728964
43 + 8728921 = 8728964
61 + 8728903 = 8728964
67 + 8728897 = 8728964
157 + 8728807 = 8728964
337 + 8728627 = 8728964
367 + 8728597 = 8728964
373 + 8728591 = 8728964

Showing the first eight; more decompositions exist.
