Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477704, here are decompositions:

7 + 31477697 = 31477704
47 + 31477657 = 31477704
101 + 31477603 = 31477704
127 + 31477577 = 31477704
151 + 31477553 = 31477704
191 + 31477513 = 31477704
197 + 31477507 = 31477704
257 + 31477447 = 31477704

Showing the first eight; more decompositions exist.
