Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650228, here are decompositions:

5 + 8650223 = 8650228
11 + 8650217 = 8650228
17 + 8650211 = 8650228
107 + 8650121 = 8650228
317 + 8649911 = 8650228
347 + 8649881 = 8650228
359 + 8649869 = 8650228
467 + 8649761 = 8650228

Showing the first eight; more decompositions exist.
