Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742660, here are decompositions:

7 + 8742653 = 8742660
23 + 8742637 = 8742660
37 + 8742623 = 8742660
83 + 8742577 = 8742660
89 + 8742571 = 8742660
109 + 8742551 = 8742660
131 + 8742529 = 8742660
149 + 8742511 = 8742660

Showing the first eight; more decompositions exist.
