Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494578, here are decompositions:

11 + 494567 = 494578
17 + 494561 = 494578
59 + 494519 = 494578
107 + 494471 = 494578
137 + 494441 = 494578
191 + 494387 = 494578
197 + 494381 = 494578
251 + 494327 = 494578

Showing the first eight; more decompositions exist.
