Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494380, here are decompositions:

11 + 494369 = 494380
53 + 494327 = 494380
113 + 494267 = 494380
167 + 494213 = 494380
233 + 494147 = 494380
239 + 494141 = 494380
251 + 494129 = 494380
311 + 494069 = 494380

Showing the first eight; more decompositions exist.
