Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549658, here are decompositions:

17 + 549641 = 549658
71 + 549587 = 549658
89 + 549569 = 549658
107 + 549551 = 549658
149 + 549509 = 549658
227 + 549431 = 549658
401 + 549257 = 549658
491 + 549167 = 549658

Showing the first eight; more decompositions exist.
