Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501790, here are decompositions:

11 + 501779 = 501790
59 + 501731 = 501790
71 + 501719 = 501790
83 + 501707 = 501790
89 + 501701 = 501790
131 + 501659 = 501790
167 + 501623 = 501790
173 + 501617 = 501790

Showing the first eight; more decompositions exist.
