Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576944, here are decompositions:

13 + 31576931 = 31576944
43 + 31576901 = 31576944
53 + 31576891 = 31576944
101 + 31576843 = 31576944
167 + 31576777 = 31576944
193 + 31576751 = 31576944
241 + 31576703 = 31576944
263 + 31576681 = 31576944

Showing the first eight; more decompositions exist.
