Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730660, here are decompositions:

11 + 8730649 = 8730660
31 + 8730629 = 8730660
41 + 8730619 = 8730660
53 + 8730607 = 8730660
83 + 8730577 = 8730660
101 + 8730559 = 8730660
131 + 8730529 = 8730660
149 + 8730511 = 8730660

Showing the first eight; more decompositions exist.
