Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510420, here are decompositions:

17 + 510403 = 510420
19 + 510401 = 510420
37 + 510383 = 510420
41 + 510379 = 510420
59 + 510361 = 510420
89 + 510331 = 510420
101 + 510319 = 510420
109 + 510311 = 510420

Showing the first eight; more decompositions exist.
