Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513812, here are decompositions:

31 + 513781 = 513812
43 + 513769 = 513812
73 + 513739 = 513812
139 + 513673 = 513812
163 + 513649 = 513812
181 + 513631 = 513812
283 + 513529 = 513812
331 + 513481 = 513812

Showing the first eight; more decompositions exist.
