Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548646, here are decompositions:

17 + 548629 = 548646
23 + 548623 = 548646
67 + 548579 = 548646
79 + 548567 = 548646
89 + 548557 = 548646
103 + 548543 = 548646
113 + 548533 = 548646
127 + 548519 = 548646

Showing the first eight; more decompositions exist.
