Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512746, here are decompositions:

5 + 512741 = 512746
29 + 512717 = 512746
83 + 512663 = 512746
89 + 512657 = 512746
137 + 512609 = 512746
149 + 512597 = 512746
167 + 512579 = 512746
173 + 512573 = 512746

Showing the first eight; more decompositions exist.
