Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513686, here are decompositions:

3 + 513683 = 513686
7 + 513679 = 513686
13 + 513673 = 513686
37 + 513649 = 513686
157 + 513529 = 513686
367 + 513319 = 513686
373 + 513313 = 513686
379 + 513307 = 513686

Showing the first eight; more decompositions exist.
