Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565134, here are decompositions:

5 + 31565129 = 31565134
17 + 31565117 = 31565134
47 + 31565087 = 31565134
191 + 31564943 = 31565134
281 + 31564853 = 31565134
353 + 31564781 = 31565134
521 + 31564613 = 31565134
617 + 31564517 = 31565134

Showing the first eight; more decompositions exist.
