Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530436, here are decompositions:

17 + 31530419 = 31530436
53 + 31530383 = 31530436
59 + 31530377 = 31530436
89 + 31530347 = 31530436
167 + 31530269 = 31530436
233 + 31530203 = 31530436
239 + 31530197 = 31530436
263 + 31530173 = 31530436

Showing the first eight; more decompositions exist.
