Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502240, here are decompositions:

3 + 502237 = 502240
23 + 502217 = 502240
59 + 502181 = 502240
107 + 502133 = 502240
197 + 502043 = 502240
227 + 502013 = 502240
239 + 502001 = 502240
269 + 501971 = 502240

Showing the first eight; more decompositions exist.
