Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493668, here are decompositions:

11 + 493657 = 493668
41 + 493627 = 493668
47 + 493621 = 493668
61 + 493607 = 493668
89 + 493579 = 493668
101 + 493567 = 493668
127 + 493541 = 493668
137 + 493531 = 493668

Showing the first eight; more decompositions exist.
