Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513726, here are decompositions:

7 + 513719 = 513726
29 + 513697 = 513726
43 + 513683 = 513726
47 + 513679 = 513726
53 + 513673 = 513726
193 + 513533 = 513726
197 + 513529 = 513726
307 + 513419 = 513726

Showing the first eight; more decompositions exist.
