Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595236, here are decompositions:

17 + 31595219 = 31595236
47 + 31595189 = 31595236
59 + 31595177 = 31595236
173 + 31595063 = 31595236
227 + 31595009 = 31595236
317 + 31594919 = 31595236
353 + 31594883 = 31595236
359 + 31594877 = 31595236

Showing the first eight; more decompositions exist.
