Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512978, here are decompositions:

19 + 512959 = 512978
61 + 512917 = 512978
79 + 512899 = 512978
157 + 512821 = 512978
181 + 512797 = 512978
199 + 512779 = 512978
211 + 512767 = 512978
307 + 512671 = 512978

Showing the first eight; more decompositions exist.
