Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530220, here are decompositions:

17 + 31530203 = 31530220
23 + 31530197 = 31530220
47 + 31530173 = 31530220
191 + 31530029 = 31530220
251 + 31529969 = 31530220
401 + 31529819 = 31530220
503 + 31529717 = 31530220
569 + 31529651 = 31530220

Showing the first eight; more decompositions exist.
