Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493278, here are decompositions:

29 + 493249 = 493278
47 + 493231 = 493278
59 + 493219 = 493278
61 + 493217 = 493278
67 + 493211 = 493278
101 + 493177 = 493278
109 + 493169 = 493278
131 + 493147 = 493278

Showing the first eight; more decompositions exist.
