Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549826, here are decompositions:

59 + 549767 = 549826
89 + 549737 = 549826
107 + 549719 = 549826
113 + 549713 = 549826
239 + 549587 = 549826
257 + 549569 = 549826
293 + 549533 = 549826
317 + 549509 = 549826

Showing the first eight; more decompositions exist.
