Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493788, here are decompositions:

11 + 493777 = 493788
41 + 493747 = 493788
59 + 493729 = 493788
67 + 493721 = 493788
79 + 493709 = 493788
131 + 493657 = 493788
167 + 493621 = 493788
181 + 493607 = 493788

Showing the first eight; more decompositions exist.
