Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501902, here are decompositions:

13 + 501889 = 501902
61 + 501841 = 501902
73 + 501829 = 501902
199 + 501703 = 501902
211 + 501691 = 501902
409 + 501493 = 501902
439 + 501463 = 501902
631 + 501271 = 501902

Showing the first eight; more decompositions exist.
