Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465906, here are decompositions:

149 + 31465757 = 31465906
179 + 31465727 = 31465906
233 + 31465673 = 31465906
257 + 31465649 = 31465906
359 + 31465547 = 31465906
617 + 31465289 = 31465906
683 + 31465223 = 31465906
1097 + 31464809 = 31465906

Showing the first eight; more decompositions exist.
