Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595664, here are decompositions:

7 + 31595657 = 31595664
11 + 31595653 = 31595664
53 + 31595611 = 31595664
71 + 31595593 = 31595664
83 + 31595581 = 31595664
97 + 31595567 = 31595664
181 + 31595483 = 31595664
197 + 31595467 = 31595664

Showing the first eight; more decompositions exist.
