Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549790, here are decompositions:

23 + 549767 = 549790
41 + 549749 = 549790
53 + 549737 = 549790
71 + 549719 = 549790
83 + 549707 = 549790
89 + 549701 = 549790
107 + 549683 = 549790
149 + 549641 = 549790

Showing the first eight; more decompositions exist.
