Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595328, here are decompositions:

109 + 31595219 = 31595328
139 + 31595189 = 31595328
151 + 31595177 = 31595328
227 + 31595101 = 31595328
269 + 31595059 = 31595328
307 + 31595021 = 31595328
337 + 31594991 = 31595328
367 + 31594961 = 31595328

Showing the first eight; more decompositions exist.
