Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493646, here are decompositions:

3 + 493643 = 493646
19 + 493627 = 493646
67 + 493579 = 493646
73 + 493573 = 493646
79 + 493567 = 493646
199 + 493447 = 493646
277 + 493369 = 493646
313 + 493333 = 493646

Showing the first eight; more decompositions exist.
