Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494872, here are decompositions:

23 + 494849 = 494872
29 + 494843 = 494872
83 + 494789 = 494872
89 + 494783 = 494872
113 + 494759 = 494872
149 + 494723 = 494872
173 + 494699 = 494872
179 + 494693 = 494872

Showing the first eight; more decompositions exist.
