Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477512, here are decompositions:

5 + 31477507 = 31477512
29 + 31477483 = 31477512
83 + 31477429 = 31477512
89 + 31477423 = 31477512
113 + 31477399 = 31477512
163 + 31477349 = 31477512
191 + 31477321 = 31477512
211 + 31477301 = 31477512

Showing the first eight; more decompositions exist.
