Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477674, here are decompositions:

5 + 31477669 = 31477674
17 + 31477657 = 31477674
71 + 31477603 = 31477674
97 + 31477577 = 31477674
103 + 31477571 = 31477674
113 + 31477561 = 31477674
131 + 31477543 = 31477674
167 + 31477507 = 31477674

Showing the first eight; more decompositions exist.
