Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732660, here are decompositions:

7 + 8732653 = 8732660
19 + 8732641 = 8732660
61 + 8732599 = 8732660
67 + 8732593 = 8732660
109 + 8732551 = 8732660
199 + 8732461 = 8732660
229 + 8732431 = 8732660
421 + 8732239 = 8732660

Showing the first eight; more decompositions exist.
