Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549628, here are decompositions:

5 + 549623 = 549628
41 + 549587 = 549628
59 + 549569 = 549628
179 + 549449 = 549628
197 + 549431 = 549628
347 + 549281 = 549628
461 + 549167 = 549628
467 + 549161 = 549628

Showing the first eight; more decompositions exist.
