Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477734, here are decompositions:

5 + 31477729 = 31477734
11 + 31477723 = 31477734
17 + 31477717 = 31477734
23 + 31477711 = 31477734
37 + 31477697 = 31477734
131 + 31477603 = 31477734
151 + 31477583 = 31477734
157 + 31477577 = 31477734

Showing the first eight; more decompositions exist.
