Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530588, here are decompositions:

17 + 31530571 = 31530588
101 + 31530487 = 31530588
109 + 31530479 = 31530588
137 + 31530451 = 31530588
151 + 31530437 = 31530588
179 + 31530409 = 31530588
197 + 31530391 = 31530588
211 + 31530377 = 31530588

Showing the first eight; more decompositions exist.
