Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581496, here are decompositions:

5 + 581491 = 581496
23 + 581473 = 581496
37 + 581459 = 581496
53 + 581443 = 581496
67 + 581429 = 581496
89 + 581407 = 581496
103 + 581393 = 581496
127 + 581369 = 581496

Showing the first eight; more decompositions exist.
