Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530532, here are decompositions:

53 + 31530479 = 31530532
113 + 31530419 = 31530532
149 + 31530383 = 31530532
191 + 31530341 = 31530532
239 + 31530293 = 31530532
263 + 31530269 = 31530532
359 + 31530173 = 31530532
389 + 31530143 = 31530532

Showing the first eight; more decompositions exist.
