Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465726, here are decompositions:

29 + 31465697 = 31465726
53 + 31465673 = 31465726
107 + 31465619 = 31465726
179 + 31465547 = 31465726
197 + 31465529 = 31465726
503 + 31465223 = 31465726
1109 + 31464617 = 31465726
1217 + 31464509 = 31465726

Showing the first eight; more decompositions exist.
