Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494686, here are decompositions:

47 + 494639 = 494686
167 + 494519 = 494686
317 + 494369 = 494686
359 + 494327 = 494686
419 + 494267 = 494686
449 + 494237 = 494686
557 + 494129 = 494686
593 + 494093 = 494686

Showing the first eight; more decompositions exist.
