Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508390, here are decompositions:

17 + 508373 = 508390
23 + 508367 = 508390
41 + 508349 = 508390
59 + 508331 = 508390
89 + 508301 = 508390
131 + 508259 = 508390
167 + 508223 = 508390
293 + 508097 = 508390

Showing the first eight; more decompositions exist.
