Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493720, here are decompositions:

11 + 493709 = 493720
113 + 493607 = 493720
137 + 493583 = 493720
179 + 493541 = 493720
197 + 493523 = 493720
239 + 493481 = 493720
257 + 493463 = 493720
263 + 493457 = 493720

Showing the first eight; more decompositions exist.
