Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540932, here are decompositions:

11 + 31540921 = 31540932
61 + 31540871 = 31540932
109 + 31540823 = 31540932
149 + 31540783 = 31540932
223 + 31540709 = 31540932
233 + 31540699 = 31540932
239 + 31540693 = 31540932
263 + 31540669 = 31540932

Showing the first eight; more decompositions exist.
