Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477606, here are decompositions:

3 + 31477603 = 31477606
23 + 31477583 = 31477606
29 + 31477577 = 31477606
53 + 31477553 = 31477606
179 + 31477427 = 31477606
227 + 31477379 = 31477606
257 + 31477349 = 31477606
317 + 31477289 = 31477606

Showing the first eight; more decompositions exist.
