Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576932, here are decompositions:

31 + 31576901 = 31576932
41 + 31576891 = 31576932
43 + 31576889 = 31576932
89 + 31576843 = 31576932
173 + 31576759 = 31576932
181 + 31576751 = 31576932
193 + 31576739 = 31576932
223 + 31576709 = 31576932

Showing the first eight; more decompositions exist.
