Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516408, here are decompositions:

17 + 516391 = 516408
31 + 516377 = 516408
37 + 516371 = 516408
47 + 516361 = 516408
59 + 516349 = 516408
89 + 516319 = 516408
131 + 516277 = 516408
157 + 516251 = 516408

Showing the first eight; more decompositions exist.
