Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494140, here are decompositions:

11 + 494129 = 494140
47 + 494093 = 494140
71 + 494069 = 494140
89 + 494051 = 494140
167 + 493973 = 494140
173 + 493967 = 494140
263 + 493877 = 494140
281 + 493859 = 494140

Showing the first eight; more decompositions exist.
