Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494146, here are decompositions:

5 + 494141 = 494146
17 + 494129 = 494146
53 + 494093 = 494146
167 + 493979 = 494146
173 + 493973 = 494146
179 + 493967 = 494146
227 + 493919 = 494146
269 + 493877 = 494146

Showing the first eight; more decompositions exist.
