Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513992, here are decompositions:

151 + 513841 = 513992
163 + 513829 = 513992
211 + 513781 = 513992
223 + 513769 = 513992
313 + 513679 = 513992
463 + 513529 = 513992
673 + 513319 = 513992
709 + 513283 = 513992

Showing the first eight; more decompositions exist.
