Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493590, here are decompositions:

7 + 493583 = 493590
11 + 493579 = 493590
17 + 493573 = 493590
23 + 493567 = 493590
59 + 493531 = 493590
67 + 493523 = 493590
109 + 493481 = 493590
127 + 493463 = 493590

Showing the first eight; more decompositions exist.
