Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565932, here are decompositions:

3 + 31565929 = 31565932
239 + 31565693 = 31565932
269 + 31565663 = 31565932
509 + 31565423 = 31565932
521 + 31565411 = 31565932
641 + 31565291 = 31565932
653 + 31565279 = 31565932
683 + 31565249 = 31565932

Showing the first eight; more decompositions exist.
