Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595292, here are decompositions:

13 + 31595279 = 31595292
19 + 31595273 = 31595292
41 + 31595251 = 31595292
73 + 31595219 = 31595292
83 + 31595209 = 31595292
103 + 31595189 = 31595292
151 + 31595141 = 31595292
191 + 31595101 = 31595292

Showing the first eight; more decompositions exist.
