Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549320, here are decompositions:

7 + 549313 = 549320
61 + 549259 = 549320
73 + 549247 = 549320
127 + 549193 = 549320
151 + 549169 = 549320
157 + 549163 = 549320
181 + 549139 = 549320
199 + 549121 = 549320

Showing the first eight; more decompositions exist.
