Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501898, here are decompositions:

71 + 501827 = 501898
167 + 501731 = 501898
179 + 501719 = 501898
191 + 501707 = 501898
197 + 501701 = 501898
239 + 501659 = 501898
281 + 501617 = 501898
479 + 501419 = 501898

Showing the first eight; more decompositions exist.
