Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509986, here are decompositions:

23 + 509963 = 509986
47 + 509939 = 509986
107 + 509879 = 509986
149 + 509837 = 509986
263 + 509723 = 509986
293 + 509693 = 509986
353 + 509633 = 509986
383 + 509603 = 509986

Showing the first eight; more decompositions exist.
