Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522940, here are decompositions:

3 + 31522937 = 31522940
67 + 31522873 = 31522940
193 + 31522747 = 31522940
223 + 31522717 = 31522940
271 + 31522669 = 31522940
277 + 31522663 = 31522940
283 + 31522657 = 31522940
307 + 31522633 = 31522940

Showing the first eight; more decompositions exist.
