Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509882, here are decompositions:

3 + 509879 = 509882
19 + 509863 = 509882
151 + 509731 = 509882
193 + 509689 = 509882
223 + 509659 = 509882
229 + 509653 = 509882
313 + 509569 = 509882
433 + 509449 = 509882

Showing the first eight; more decompositions exist.
