Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517982, here are decompositions:

109 + 517873 = 517982
151 + 517831 = 517982
271 + 517711 = 517982
373 + 517609 = 517982
379 + 517603 = 517982
433 + 517549 = 517982
523 + 517459 = 517982
571 + 517411 = 517982

Showing the first eight; more decompositions exist.
