Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643944, here are decompositions:

3 + 8643941 = 8643944
157 + 8643787 = 8643944
223 + 8643721 = 8643944
271 + 8643673 = 8643944
313 + 8643631 = 8643944
367 + 8643577 = 8643944
457 + 8643487 = 8643944
487 + 8643457 = 8643944

Showing the first eight; more decompositions exist.
