Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595952, here are decompositions:

23 + 31595929 = 31595952
71 + 31595881 = 31595952
79 + 31595873 = 31595952
83 + 31595869 = 31595952
181 + 31595771 = 31595952
229 + 31595723 = 31595952
233 + 31595719 = 31595952
251 + 31595701 = 31595952

Showing the first eight; more decompositions exist.
