Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595834, here are decompositions:

3 + 31595831 = 31595834
103 + 31595731 = 31595834
163 + 31595671 = 31595834
181 + 31595653 = 31595834
223 + 31595611 = 31595834
241 + 31595593 = 31595834
367 + 31595467 = 31595834
463 + 31595371 = 31595834

Showing the first eight; more decompositions exist.
