Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494390, here are decompositions:

3 + 494387 = 494390
7 + 494383 = 494390
31 + 494359 = 494390
37 + 494353 = 494390
73 + 494317 = 494390
103 + 494287 = 494390
109 + 494281 = 494390
139 + 494251 = 494390

Showing the first eight; more decompositions exist.
