Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512580, here are decompositions:

7 + 512573 = 512580
11 + 512569 = 512580
37 + 512543 = 512580
43 + 512537 = 512580
59 + 512521 = 512580
73 + 512507 = 512580
83 + 512497 = 512580
113 + 512467 = 512580

Showing the first eight; more decompositions exist.
