Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493806, here are decompositions:

13 + 493793 = 493806
29 + 493777 = 493806
59 + 493747 = 493806
73 + 493733 = 493806
97 + 493709 = 493806
113 + 493693 = 493806
149 + 493657 = 493806
163 + 493643 = 493806

Showing the first eight; more decompositions exist.
