Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493790, here are decompositions:

13 + 493777 = 493790
43 + 493747 = 493790
61 + 493729 = 493790
79 + 493711 = 493790
97 + 493693 = 493790
163 + 493627 = 493790
211 + 493579 = 493790
223 + 493567 = 493790

Showing the first eight; more decompositions exist.
