Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494418, here are decompositions:

5 + 494413 = 494418
11 + 494407 = 494418
31 + 494387 = 494418
37 + 494381 = 494418
59 + 494359 = 494418
101 + 494317 = 494418
131 + 494287 = 494418
137 + 494281 = 494418

Showing the first eight; more decompositions exist.
