Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501880, here are decompositions:

17 + 501863 = 501880
53 + 501827 = 501880
59 + 501821 = 501880
101 + 501779 = 501880
149 + 501731 = 501880
173 + 501707 = 501880
179 + 501701 = 501880
257 + 501623 = 501880

Showing the first eight; more decompositions exist.
