Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549838, here are decompositions:

5 + 549833 = 549838
71 + 549767 = 549838
89 + 549749 = 549838
101 + 549737 = 549838
131 + 549707 = 549838
137 + 549701 = 549838
197 + 549641 = 549838
251 + 549587 = 549838

Showing the first eight; more decompositions exist.
