Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501838, here are decompositions:

11 + 501827 = 501838
17 + 501821 = 501838
59 + 501779 = 501838
107 + 501731 = 501838
131 + 501707 = 501838
137 + 501701 = 501838
179 + 501659 = 501838
419 + 501419 = 501838

Showing the first eight; more decompositions exist.
