Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494438, here are decompositions:

31 + 494407 = 494438
79 + 494359 = 494438
97 + 494341 = 494438
151 + 494287 = 494438
157 + 494281 = 494438
181 + 494257 = 494438
271 + 494167 = 494438
331 + 494107 = 494438

Showing the first eight; more decompositions exist.
