Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520996, here are decompositions:

19 + 31520977 = 31520996
37 + 31520959 = 31520996
79 + 31520917 = 31520996
97 + 31520899 = 31520996
139 + 31520857 = 31520996
277 + 31520719 = 31520996
337 + 31520659 = 31520996
379 + 31520617 = 31520996

Showing the first eight; more decompositions exist.
