Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494636, here are decompositions:

19 + 494617 = 494636
73 + 494563 = 494636
97 + 494539 = 494636
139 + 494497 = 494636
193 + 494443 = 494636
223 + 494413 = 494636
229 + 494407 = 494636
277 + 494359 = 494636

Showing the first eight; more decompositions exist.
