Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549518, here are decompositions:

7 + 549511 = 549518
37 + 549481 = 549518
97 + 549421 = 549518
127 + 549391 = 549518
139 + 549379 = 549518
199 + 549319 = 549518
271 + 549247 = 549518
349 + 549169 = 549518

Showing the first eight; more decompositions exist.
