Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493690, here are decompositions:

47 + 493643 = 493690
83 + 493607 = 493690
107 + 493583 = 493690
149 + 493541 = 493690
167 + 493523 = 493690
227 + 493463 = 493690
233 + 493457 = 493690
257 + 493433 = 493690

Showing the first eight; more decompositions exist.
