Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531654, here are decompositions:

17 + 531637 = 531654
23 + 531631 = 531654
31 + 531623 = 531654
41 + 531613 = 531654
43 + 531611 = 531654
73 + 531581 = 531654
83 + 531571 = 531654
103 + 531551 = 531654

Showing the first eight; more decompositions exist.
