Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738660, here are decompositions:

19 + 8738641 = 8738660
79 + 8738581 = 8738660
127 + 8738533 = 8738660
211 + 8738449 = 8738660
223 + 8738437 = 8738660
277 + 8738383 = 8738660
283 + 8738377 = 8738660
367 + 8738293 = 8738660

Showing the first eight; more decompositions exist.
