Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517390, here are decompositions:

17 + 517373 = 517390
23 + 517367 = 517390
47 + 517343 = 517390
53 + 517337 = 517390
101 + 517289 = 517390
113 + 517277 = 517390
149 + 517241 = 517390
173 + 517217 = 517390

Showing the first eight; more decompositions exist.
