Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735840, here are decompositions:

13 + 8735827 = 8735840
19 + 8735821 = 8735840
31 + 8735809 = 8735840
79 + 8735761 = 8735840
97 + 8735743 = 8735840
163 + 8735677 = 8735840
277 + 8735563 = 8735840
283 + 8735557 = 8735840

Showing the first eight; more decompositions exist.
