Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493586, here are decompositions:

3 + 493583 = 493586
7 + 493579 = 493586
13 + 493573 = 493586
19 + 493567 = 493586
139 + 493447 = 493586
193 + 493393 = 493586
307 + 493279 = 493586
337 + 493249 = 493586

Showing the first eight; more decompositions exist.
