Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576950, here are decompositions:

19 + 31576931 = 31576950
59 + 31576891 = 31576950
61 + 31576889 = 31576950
107 + 31576843 = 31576950
173 + 31576777 = 31576950
191 + 31576759 = 31576950
199 + 31576751 = 31576950
211 + 31576739 = 31576950

Showing the first eight; more decompositions exist.
