Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498478, here are decompositions:

11 + 498467 = 498478
17 + 498461 = 498478
251 + 498227 = 498478
269 + 498209 = 498478
311 + 498167 = 498478
359 + 498119 = 498478
389 + 498089 = 498478
479 + 497999 = 498478

Showing the first eight; more decompositions exist.
