Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517250, here are decompositions:

7 + 517243 = 517250
43 + 517207 = 517250
61 + 517189 = 517250
67 + 517183 = 517250
73 + 517177 = 517250
163 + 517087 = 517250
271 + 516979 = 517250
277 + 516973 = 517250

Showing the first eight; more decompositions exist.
