Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513040, here are decompositions:

23 + 513017 = 513040
41 + 512999 = 513040
113 + 512927 = 513040
137 + 512903 = 513040
149 + 512891 = 513040
191 + 512849 = 513040
197 + 512843 = 513040
293 + 512747 = 513040

Showing the first eight; more decompositions exist.
