Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530502, here are decompositions:

5 + 31530497 = 31530502
23 + 31530479 = 31530502
83 + 31530419 = 31530502
191 + 31530311 = 31530502
233 + 31530269 = 31530502
359 + 31530143 = 31530502
569 + 31529933 = 31530502
659 + 31529843 = 31530502

Showing the first eight; more decompositions exist.
