Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549898, here are decompositions:

59 + 549839 = 549898
131 + 549767 = 549898
149 + 549749 = 549898
179 + 549719 = 549898
191 + 549707 = 549898
197 + 549701 = 549898
257 + 549641 = 549898
311 + 549587 = 549898

Showing the first eight; more decompositions exist.
