Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550688, here are decompositions:

31 + 550657 = 550688
37 + 550651 = 550688
67 + 550621 = 550688
79 + 550609 = 550688
157 + 550531 = 550688
199 + 550489 = 550688
241 + 550447 = 550688
337 + 550351 = 550688

Showing the first eight; more decompositions exist.
