Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493786, here are decompositions:

53 + 493733 = 493786
179 + 493607 = 493786
263 + 493523 = 493786
353 + 493433 = 493786
383 + 493403 = 493786
389 + 493397 = 493786
509 + 493277 = 493786
569 + 493217 = 493786

Showing the first eight; more decompositions exist.
