Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494236, here are decompositions:

23 + 494213 = 494236
89 + 494147 = 494236
107 + 494129 = 494236
167 + 494069 = 494236
257 + 493979 = 494236
263 + 493973 = 494236
269 + 493967 = 494236
317 + 493919 = 494236

Showing the first eight; more decompositions exist.
