Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595676, here are decompositions:

5 + 31595671 = 31595676
19 + 31595657 = 31595676
23 + 31595653 = 31595676
83 + 31595593 = 31595676
103 + 31595573 = 31595676
107 + 31595569 = 31595676
109 + 31595567 = 31595676
193 + 31595483 = 31595676

Showing the first eight; more decompositions exist.
