Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501286, here are decompositions:

29 + 501257 = 501286
53 + 501233 = 501286
83 + 501203 = 501286
89 + 501197 = 501286
113 + 501173 = 501286
197 + 501089 = 501286
257 + 501029 = 501286
353 + 500933 = 501286

Showing the first eight; more decompositions exist.
