Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640776, here are decompositions:

37 + 8640739 = 8640776
43 + 8640733 = 8640776
73 + 8640703 = 8640776
97 + 8640679 = 8640776
223 + 8640553 = 8640776
229 + 8640547 = 8640776
283 + 8640493 = 8640776
337 + 8640439 = 8640776

Showing the first eight; more decompositions exist.
