Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513012, here are decompositions:

11 + 513001 = 513012
13 + 512999 = 513012
23 + 512989 = 513012
53 + 512959 = 513012
83 + 512929 = 513012
109 + 512903 = 513012
113 + 512899 = 513012
163 + 512849 = 513012

Showing the first eight; more decompositions exist.
