Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494518, here are decompositions:

47 + 494471 = 494518
131 + 494387 = 494518
137 + 494381 = 494518
149 + 494369 = 494518
191 + 494327 = 494518
251 + 494267 = 494518
281 + 494237 = 494518
389 + 494129 = 494518

Showing the first eight; more decompositions exist.
