Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516390, here are decompositions:

13 + 516377 = 516390
19 + 516371 = 516390
29 + 516361 = 516390
31 + 516359 = 516390
41 + 516349 = 516390
67 + 516323 = 516390
71 + 516319 = 516390
97 + 516293 = 516390

Showing the first eight; more decompositions exist.
