Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516458, here are decompositions:

37 + 516421 = 516458
67 + 516391 = 516458
97 + 516361 = 516458
109 + 516349 = 516458
139 + 516319 = 516458
181 + 516277 = 516458
211 + 516247 = 516458
307 + 516151 = 516458

Showing the first eight; more decompositions exist.
