Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465696, here are decompositions:

23 + 31465673 = 31465696
47 + 31465649 = 31465696
149 + 31465547 = 31465696
167 + 31465529 = 31465696
503 + 31465193 = 31465696
887 + 31464809 = 31465696
1187 + 31464509 = 31465696
1427 + 31464269 = 31465696

Showing the first eight; more decompositions exist.
