Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549290, here are decompositions:

31 + 549259 = 549290
43 + 549247 = 549290
61 + 549229 = 549290
97 + 549193 = 549290
127 + 549163 = 549290
151 + 549139 = 549290
193 + 549097 = 549290
199 + 549091 = 549290

Showing the first eight; more decompositions exist.
