Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501872, here are decompositions:

31 + 501841 = 501872
43 + 501829 = 501872
103 + 501769 = 501872
181 + 501691 = 501872
271 + 501601 = 501872
379 + 501493 = 501872
409 + 501463 = 501872
421 + 501451 = 501872

Showing the first eight; more decompositions exist.
