Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759840, here are decompositions:

3 + 8759837 = 8759840
43 + 8759797 = 8759840
79 + 8759761 = 8759840
109 + 8759731 = 8759840
151 + 8759689 = 8759840
163 + 8759677 = 8759840
283 + 8759557 = 8759840
337 + 8759503 = 8759840

Showing the first eight; more decompositions exist.
