Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501908, here are decompositions:

19 + 501889 = 501908
67 + 501841 = 501908
79 + 501829 = 501908
139 + 501769 = 501908
271 + 501637 = 501908
307 + 501601 = 501908
331 + 501577 = 501908
397 + 501511 = 501908

Showing the first eight; more decompositions exist.
