Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494278, here are decompositions:

11 + 494267 = 494278
41 + 494237 = 494278
131 + 494147 = 494278
137 + 494141 = 494278
149 + 494129 = 494278
227 + 494051 = 494278
311 + 493967 = 494278
347 + 493931 = 494278

Showing the first eight; more decompositions exist.
