Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530606, here are decompositions:

13 + 31530593 = 31530606
17 + 31530589 = 31530606
83 + 31530523 = 31530606
109 + 31530497 = 31530606
127 + 31530479 = 31530606
197 + 31530409 = 31530606
223 + 31530383 = 31530606
229 + 31530377 = 31530606

Showing the first eight; more decompositions exist.
