Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595276, here are decompositions:

3 + 31595273 = 31595276
67 + 31595209 = 31595276
103 + 31595173 = 31595276
277 + 31594999 = 31595276
313 + 31594963 = 31595276
373 + 31594903 = 31595276
409 + 31594867 = 31595276
463 + 31594813 = 31595276

Showing the first eight; more decompositions exist.
