Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540934, here are decompositions:

13 + 31540921 = 31540934
67 + 31540867 = 31540934
97 + 31540837 = 31540934
151 + 31540783 = 31540934
211 + 31540723 = 31540934
241 + 31540693 = 31540934
277 + 31540657 = 31540934
283 + 31540651 = 31540934

Showing the first eight; more decompositions exist.
