Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498178, here are decompositions:

11 + 498167 = 498178
59 + 498119 = 498178
89 + 498089 = 498178
179 + 497999 = 498178
311 + 497867 = 498178
347 + 497831 = 498178
449 + 497729 = 498178
467 + 497711 = 498178

Showing the first eight; more decompositions exist.
