Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517230, here are decompositions:

13 + 517217 = 517230
19 + 517211 = 517230
23 + 517207 = 517230
41 + 517189 = 517230
47 + 517183 = 517230
53 + 517177 = 517230
61 + 517169 = 517230
79 + 517151 = 517230

Showing the first eight; more decompositions exist.
