Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465798, here are decompositions:

17 + 31465781 = 31465798
41 + 31465757 = 31465798
71 + 31465727 = 31465798
101 + 31465697 = 31465798
137 + 31465661 = 31465798
149 + 31465649 = 31465798
167 + 31465631 = 31465798
179 + 31465619 = 31465798

Showing the first eight; more decompositions exist.
