Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477476, here are decompositions:

29 + 31477447 = 31477476
47 + 31477429 = 31477476
53 + 31477423 = 31477476
97 + 31477379 = 31477476
127 + 31477349 = 31477476
263 + 31477213 = 31477476
269 + 31477207 = 31477476
313 + 31477163 = 31477476

Showing the first eight; more decompositions exist.
