Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615932, here are decompositions:

11 + 31615921 = 31615932
13 + 31615919 = 31615932
41 + 31615891 = 31615932
83 + 31615849 = 31615932
149 + 31615783 = 31615932
191 + 31615741 = 31615932
263 + 31615669 = 31615932
269 + 31615663 = 31615932

Showing the first eight; more decompositions exist.
