Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513986, here are decompositions:

43 + 513943 = 513986
157 + 513829 = 513986
307 + 513679 = 513986
313 + 513673 = 513986
337 + 513649 = 513986
457 + 513529 = 513986
547 + 513439 = 513986
619 + 513367 = 513986

Showing the first eight; more decompositions exist.
