Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516572, here are decompositions:

31 + 516541 = 516572
73 + 516499 = 516572
79 + 516493 = 516572
103 + 516469 = 516572
139 + 516433 = 516572
151 + 516421 = 516572
181 + 516391 = 516572
211 + 516361 = 516572

Showing the first eight; more decompositions exist.
