Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477736, here are decompositions:

7 + 31477729 = 31477736
13 + 31477723 = 31477736
19 + 31477717 = 31477736
67 + 31477669 = 31477736
79 + 31477657 = 31477736
193 + 31477543 = 31477736
223 + 31477513 = 31477736
229 + 31477507 = 31477736

Showing the first eight; more decompositions exist.
