Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517220, here are decompositions:

3 + 517217 = 517220
13 + 517207 = 517220
31 + 517189 = 517220
37 + 517183 = 517220
43 + 517177 = 517220
139 + 517081 = 517220
229 + 516991 = 517220
241 + 516979 = 517220

Showing the first eight; more decompositions exist.
