Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549784, here are decompositions:

17 + 549767 = 549784
47 + 549737 = 549784
71 + 549713 = 549784
83 + 549701 = 549784
101 + 549683 = 549784
197 + 549587 = 549784
233 + 549551 = 549784
251 + 549533 = 549784

Showing the first eight; more decompositions exist.
