Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649746, here are decompositions:

43 + 8649703 = 8649746
109 + 8649637 = 8649746
229 + 8649517 = 8649746
277 + 8649469 = 8649746
283 + 8649463 = 8649746
337 + 8649409 = 8649746
379 + 8649367 = 8649746
397 + 8649349 = 8649746

Showing the first eight; more decompositions exist.
