Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738066, here are decompositions:

13 + 8738053 = 8738066
19 + 8738047 = 8738066
193 + 8737873 = 8738066
199 + 8737867 = 8738066
223 + 8737843 = 8738066
277 + 8737789 = 8738066
283 + 8737783 = 8738066
349 + 8737717 = 8738066

Showing the first eight; more decompositions exist.
