Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512526, here are decompositions:

5 + 512521 = 512526
19 + 512507 = 512526
23 + 512503 = 512526
29 + 512497 = 512526
59 + 512467 = 512526
83 + 512443 = 512526
97 + 512429 = 512526
107 + 512419 = 512526

Showing the first eight; more decompositions exist.
