Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576016, here are decompositions:

7 + 31576009 = 31576016
13 + 31576003 = 31576016
79 + 31575937 = 31576016
139 + 31575877 = 31576016
193 + 31575823 = 31576016
223 + 31575793 = 31576016
349 + 31575667 = 31576016
379 + 31575637 = 31576016

Showing the first eight; more decompositions exist.
