Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522690, here are decompositions:

11 + 522679 = 522690
13 + 522677 = 522690
17 + 522673 = 522690
29 + 522661 = 522690
31 + 522659 = 522690
53 + 522637 = 522690
67 + 522623 = 522690
89 + 522601 = 522690

Showing the first eight; more decompositions exist.
