Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477436, here are decompositions:

7 + 31477429 = 31477436
13 + 31477423 = 31477436
37 + 31477399 = 31477436
223 + 31477213 = 31477436
229 + 31477207 = 31477436
337 + 31477099 = 31477436
373 + 31477063 = 31477436
379 + 31477057 = 31477436

Showing the first eight; more decompositions exist.
