Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759640, here are decompositions:

37 + 8759603 = 8759640
59 + 8759581 = 8759640
61 + 8759579 = 8759640
83 + 8759557 = 8759640
137 + 8759503 = 8759640
173 + 8759467 = 8759640
181 + 8759459 = 8759640
233 + 8759407 = 8759640

Showing the first eight; more decompositions exist.
