Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576922, here are decompositions:

31 + 31576891 = 31576922
79 + 31576843 = 31576922
163 + 31576759 = 31576922
241 + 31576681 = 31576922
283 + 31576639 = 31576922
373 + 31576549 = 31576922
439 + 31576483 = 31576922
463 + 31576459 = 31576922

Showing the first eight; more decompositions exist.
