Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500286, here are decompositions:

29 + 500257 = 500286
37 + 500249 = 500286
47 + 500239 = 500286
53 + 500233 = 500286
89 + 500197 = 500286
107 + 500179 = 500286
109 + 500177 = 500286
113 + 500173 = 500286

Showing the first eight; more decompositions exist.
