Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595964, here are decompositions:

83 + 31595881 = 31595964
97 + 31595867 = 31595964
131 + 31595833 = 31595964
157 + 31595807 = 31595964
181 + 31595783 = 31595964
193 + 31595771 = 31595964
233 + 31595731 = 31595964
241 + 31595723 = 31595964

Showing the first eight; more decompositions exist.
