Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512556, here are decompositions:

13 + 512543 = 512556
19 + 512537 = 512556
53 + 512503 = 512556
59 + 512497 = 512556
89 + 512467 = 512556
113 + 512443 = 512556
127 + 512429 = 512556
137 + 512419 = 512556

Showing the first eight; more decompositions exist.
