Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737666, here are decompositions:

83 + 8737583 = 8737666
89 + 8737577 = 8737666
137 + 8737529 = 8737666
233 + 8737433 = 8737666
239 + 8737427 = 8737666
293 + 8737373 = 8737666
317 + 8737349 = 8737666
389 + 8737277 = 8737666

Showing the first eight; more decompositions exist.
