Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549478, here are decompositions:

29 + 549449 = 549478
47 + 549431 = 549478
197 + 549281 = 549478
257 + 549221 = 549478
311 + 549167 = 549478
317 + 549161 = 549478
389 + 549089 = 549478
467 + 549011 = 549478

Showing the first eight; more decompositions exist.
