Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477706, here are decompositions:

37 + 31477669 = 31477706
103 + 31477603 = 31477706
157 + 31477549 = 31477706
163 + 31477543 = 31477706
193 + 31477513 = 31477706
199 + 31477507 = 31477706
223 + 31477483 = 31477706
277 + 31477429 = 31477706

Showing the first eight; more decompositions exist.
