Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549940, here are decompositions:

3 + 549937 = 549940
29 + 549911 = 549940
101 + 549839 = 549940
107 + 549833 = 549940
173 + 549767 = 549940
191 + 549749 = 549940
227 + 549713 = 549940
233 + 549707 = 549940

Showing the first eight; more decompositions exist.
