Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494388, here are decompositions:

5 + 494383 = 494388
7 + 494381 = 494388
19 + 494369 = 494388
29 + 494359 = 494388
47 + 494341 = 494388
61 + 494327 = 494388
71 + 494317 = 494388
101 + 494287 = 494388

Showing the first eight; more decompositions exist.
