Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517420, here are decompositions:

3 + 517417 = 517420
17 + 517403 = 517420
47 + 517373 = 517420
53 + 517367 = 517420
83 + 517337 = 517420
131 + 517289 = 517420
179 + 517241 = 517420
191 + 517229 = 517420

Showing the first eight; more decompositions exist.
