Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494386, here are decompositions:

3 + 494383 = 494386
5 + 494381 = 494386
17 + 494369 = 494386
59 + 494327 = 494386
149 + 494237 = 494386
173 + 494213 = 494386
239 + 494147 = 494386
257 + 494129 = 494386

Showing the first eight; more decompositions exist.
