Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608696, here are decompositions:

29 + 31608667 = 31608696
107 + 31608589 = 31608696
109 + 31608587 = 31608696
167 + 31608529 = 31608696
199 + 31608497 = 31608696
269 + 31608427 = 31608696
347 + 31608349 = 31608696
359 + 31608337 = 31608696

Showing the first eight; more decompositions exist.
