Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565704, here are decompositions:

3 + 31565701 = 31565704
11 + 31565693 = 31565704
41 + 31565663 = 31565704
101 + 31565603 = 31565704
281 + 31565423 = 31565704
293 + 31565411 = 31565704
353 + 31565351 = 31565704
587 + 31565117 = 31565704

Showing the first eight; more decompositions exist.
