Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512548, here are decompositions:

5 + 512543 = 512548
11 + 512537 = 512548
17 + 512531 = 512548
41 + 512507 = 512548
227 + 512321 = 512548
401 + 512147 = 512548
557 + 511991 = 512548
587 + 511961 = 512548

Showing the first eight; more decompositions exist.
