Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494474, here are decompositions:

3 + 494471 = 494474
31 + 494443 = 494474
61 + 494413 = 494474
67 + 494407 = 494474
157 + 494317 = 494474
193 + 494281 = 494474
223 + 494251 = 494474
283 + 494191 = 494474

Showing the first eight; more decompositions exist.
