Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530834, here are decompositions:

7 + 31530827 = 31530834
37 + 31530797 = 31530834
61 + 31530773 = 31530834
131 + 31530703 = 31530834
151 + 31530683 = 31530834
173 + 31530661 = 31530834
191 + 31530643 = 31530834
193 + 31530641 = 31530834

Showing the first eight; more decompositions exist.
