Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512998, here are decompositions:

71 + 512927 = 512998
107 + 512891 = 512998
149 + 512849 = 512998
179 + 512819 = 512998
251 + 512747 = 512998
257 + 512741 = 512998
281 + 512717 = 512998
389 + 512609 = 512998

Showing the first eight; more decompositions exist.
