Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595942, here are decompositions:

13 + 31595929 = 31595942
61 + 31595881 = 31595942
73 + 31595869 = 31595942
109 + 31595833 = 31595942
211 + 31595731 = 31595942
223 + 31595719 = 31595942
241 + 31595701 = 31595942
271 + 31595671 = 31595942

Showing the first eight; more decompositions exist.
