Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663240, here are decompositions:

31 + 8663209 = 8663240
139 + 8663101 = 8663240
151 + 8663089 = 8663240
277 + 8662963 = 8663240
349 + 8662891 = 8663240
373 + 8662867 = 8663240
409 + 8662831 = 8663240
433 + 8662807 = 8663240

Showing the first eight; more decompositions exist.
