Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595282, here are decompositions:

3 + 31595279 = 31595282
31 + 31595251 = 31595282
73 + 31595209 = 31595282
109 + 31595173 = 31595282
181 + 31595101 = 31595282
223 + 31595059 = 31595282
283 + 31594999 = 31595282
379 + 31594903 = 31595282

Showing the first eight; more decompositions exist.
