Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501878, here are decompositions:

37 + 501841 = 501878
61 + 501817 = 501878
109 + 501769 = 501878
241 + 501637 = 501878
277 + 501601 = 501878
367 + 501511 = 501878
607 + 501271 = 501878
661 + 501217 = 501878

Showing the first eight; more decompositions exist.
