Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576962, here are decompositions:

5 + 31576957 = 31576962
13 + 31576949 = 31576962
31 + 31576931 = 31576962
61 + 31576901 = 31576962
71 + 31576891 = 31576962
73 + 31576889 = 31576962
211 + 31576751 = 31576962
223 + 31576739 = 31576962

Showing the first eight; more decompositions exist.
