Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494398, here are decompositions:

11 + 494387 = 494398
17 + 494381 = 494398
29 + 494369 = 494398
71 + 494327 = 494398
131 + 494267 = 494398
251 + 494147 = 494398
257 + 494141 = 494398
269 + 494129 = 494398

Showing the first eight; more decompositions exist.
