Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494618, here are decompositions:

31 + 494587 = 494618
79 + 494539 = 494618
97 + 494521 = 494618
211 + 494407 = 494618
277 + 494341 = 494618
331 + 494287 = 494618
337 + 494281 = 494618
349 + 494269 = 494618

Showing the first eight; more decompositions exist.
