Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530466, here are decompositions:

29 + 31530437 = 31530466
47 + 31530419 = 31530466
83 + 31530383 = 31530466
89 + 31530377 = 31530466
173 + 31530293 = 31530466
197 + 31530269 = 31530466
263 + 31530203 = 31530466
269 + 31530197 = 31530466

Showing the first eight; more decompositions exist.
