Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494542, here are decompositions:

3 + 494539 = 494542
23 + 494519 = 494542
71 + 494471 = 494542
101 + 494441 = 494542
173 + 494369 = 494542
401 + 494141 = 494542
449 + 494093 = 494542
491 + 494051 = 494542

Showing the first eight; more decompositions exist.
