Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758840, here are decompositions:

17 + 8758823 = 8758840
47 + 8758793 = 8758840
53 + 8758787 = 8758840
59 + 8758781 = 8758840
107 + 8758733 = 8758840
179 + 8758661 = 8758840
257 + 8758583 = 8758840
263 + 8758577 = 8758840

Showing the first eight; more decompositions exist.
