Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740680, here are decompositions:

23 + 8740657 = 8740680
31 + 8740649 = 8740680
37 + 8740643 = 8740680
73 + 8740607 = 8740680
89 + 8740591 = 8740680
101 + 8740579 = 8740680
103 + 8740577 = 8740680
139 + 8740541 = 8740680

Showing the first eight; more decompositions exist.
