Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494430, here are decompositions:

17 + 494413 = 494430
23 + 494407 = 494430
43 + 494387 = 494430
47 + 494383 = 494430
61 + 494369 = 494430
71 + 494359 = 494430
89 + 494341 = 494430
103 + 494327 = 494430

Showing the first eight; more decompositions exist.
