Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549442, here are decompositions:

11 + 549431 = 549442
239 + 549203 = 549442
281 + 549161 = 549442
293 + 549149 = 549442
353 + 549089 = 549442
419 + 549023 = 549442
431 + 549011 = 549442
479 + 548963 = 549442

Showing the first eight; more decompositions exist.
