Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493906, here are decompositions:

29 + 493877 = 493906
47 + 493859 = 493906
53 + 493853 = 493906
89 + 493817 = 493906
113 + 493793 = 493906
173 + 493733 = 493906
197 + 493709 = 493906
263 + 493643 = 493906

Showing the first eight; more decompositions exist.
