Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465734, here are decompositions:

7 + 31465727 = 31465734
23 + 31465711 = 31465734
37 + 31465697 = 31465734
61 + 31465673 = 31465734
71 + 31465663 = 31465734
73 + 31465661 = 31465734
103 + 31465631 = 31465734
163 + 31465571 = 31465734

Showing the first eight; more decompositions exist.
