Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740690, here are decompositions:

11 + 8740679 = 8740690
41 + 8740649 = 8740690
47 + 8740643 = 8740690
83 + 8740607 = 8740690
113 + 8740577 = 8740690
131 + 8740559 = 8740690
149 + 8740541 = 8740690
173 + 8740517 = 8740690

Showing the first eight; more decompositions exist.
