Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549862, here are decompositions:

23 + 549839 = 549862
29 + 549833 = 549862
113 + 549749 = 549862
149 + 549713 = 549862
179 + 549683 = 549862
239 + 549623 = 549862
293 + 549569 = 549862
311 + 549551 = 549862

Showing the first eight; more decompositions exist.
