Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520882, here are decompositions:

31 + 31520851 = 31520882
163 + 31520719 = 31520882
181 + 31520701 = 31520882
223 + 31520659 = 31520882
313 + 31520569 = 31520882
373 + 31520509 = 31520882
709 + 31520173 = 31520882
823 + 31520059 = 31520882

Showing the first eight; more decompositions exist.
