Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493568, here are decompositions:

37 + 493531 = 493568
199 + 493369 = 493568
277 + 493291 = 493568
337 + 493231 = 493568
349 + 493219 = 493568
367 + 493201 = 493568
409 + 493159 = 493568
421 + 493147 = 493568

Showing the first eight; more decompositions exist.
