Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516554, here are decompositions:

13 + 516541 = 516554
37 + 516517 = 516554
61 + 516493 = 516554
97 + 516457 = 516554
163 + 516391 = 516554
193 + 516361 = 516554
271 + 516283 = 516554
277 + 516277 = 516554

Showing the first eight; more decompositions exist.
