Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549946, here are decompositions:

3 + 549943 = 549946
83 + 549863 = 549946
107 + 549839 = 549946
113 + 549833 = 549946
179 + 549767 = 549946
197 + 549749 = 549946
227 + 549719 = 549946
233 + 549713 = 549946

Showing the first eight; more decompositions exist.
