Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494188, here are decompositions:

41 + 494147 = 494188
47 + 494141 = 494188
59 + 494129 = 494188
137 + 494051 = 494188
251 + 493937 = 494188
257 + 493931 = 494188
269 + 493919 = 494188
311 + 493877 = 494188

Showing the first eight; more decompositions exist.
