Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680778, here are decompositions:

37 + 8680741 = 8680778
61 + 8680717 = 8680778
79 + 8680699 = 8680778
109 + 8680669 = 8680778
277 + 8680501 = 8680778
307 + 8680471 = 8680778
409 + 8680369 = 8680778
577 + 8680201 = 8680778

Showing the first eight; more decompositions exist.
