Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595696, here are decompositions:

43 + 31595653 = 31595696
103 + 31595593 = 31595696
127 + 31595569 = 31595696
229 + 31595467 = 31595696
313 + 31595383 = 31595696
487 + 31595209 = 31595696
523 + 31595173 = 31595696
709 + 31594987 = 31595696

Showing the first eight; more decompositions exist.
