Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595366, here are decompositions:

3 + 31595363 = 31595366
157 + 31595209 = 31595366
193 + 31595173 = 31595366
307 + 31595059 = 31595366
367 + 31594999 = 31595366
379 + 31594987 = 31595366
463 + 31594903 = 31595366
499 + 31594867 = 31595366

Showing the first eight; more decompositions exist.
