Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494782, here are decompositions:

23 + 494759 = 494782
59 + 494723 = 494782
83 + 494699 = 494782
89 + 494693 = 494782
131 + 494651 = 494782
173 + 494609 = 494782
191 + 494591 = 494782
263 + 494519 = 494782

Showing the first eight; more decompositions exist.
