Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517240, here are decompositions:

11 + 517229 = 517240
23 + 517217 = 517240
29 + 517211 = 517240
71 + 517169 = 517240
89 + 517151 = 517240
149 + 517091 = 517240
167 + 517073 = 517240
173 + 517067 = 517240

Showing the first eight; more decompositions exist.
