Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517826, here are decompositions:

3 + 517823 = 517826
79 + 517747 = 517826
97 + 517729 = 517826
109 + 517717 = 517826
223 + 517603 = 517826
229 + 517597 = 517826
277 + 517549 = 517826
313 + 517513 = 517826

Showing the first eight; more decompositions exist.
