Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549974, here are decompositions:

31 + 549943 = 549974
37 + 549937 = 549974
97 + 549877 = 549974
157 + 549817 = 549974
223 + 549751 = 549974
241 + 549733 = 549974
283 + 549691 = 549974
307 + 549667 = 549974

Showing the first eight; more decompositions exist.
