Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493420, here are decompositions:

17 + 493403 = 493420
23 + 493397 = 493420
107 + 493313 = 493420
227 + 493193 = 493420
251 + 493169 = 493420
281 + 493139 = 493420
293 + 493127 = 493420
311 + 493109 = 493420

Showing the first eight; more decompositions exist.
