Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494158, here are decompositions:

11 + 494147 = 494158
17 + 494141 = 494158
29 + 494129 = 494158
89 + 494069 = 494158
107 + 494051 = 494158
179 + 493979 = 494158
191 + 493967 = 494158
227 + 493931 = 494158

Showing the first eight; more decompositions exist.
