Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477794, here are decompositions:

13 + 31477781 = 31477794
41 + 31477753 = 31477794
43 + 31477751 = 31477794
71 + 31477723 = 31477794
83 + 31477711 = 31477794
97 + 31477697 = 31477794
137 + 31477657 = 31477794
191 + 31477603 = 31477794

Showing the first eight; more decompositions exist.
