Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500986, here are decompositions:

29 + 500957 = 500986
53 + 500933 = 500986
113 + 500873 = 500986
179 + 500807 = 500986
257 + 500729 = 500986
263 + 500723 = 500986
293 + 500693 = 500986
383 + 500603 = 500986

Showing the first eight; more decompositions exist.
