Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512550, here are decompositions:

7 + 512543 = 512550
13 + 512537 = 512550
19 + 512531 = 512550
29 + 512521 = 512550
43 + 512507 = 512550
47 + 512503 = 512550
53 + 512497 = 512550
83 + 512467 = 512550

Showing the first eight; more decompositions exist.
