Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610348, here are decompositions:

31 + 31610317 = 31610348
61 + 31610287 = 31610348
79 + 31610269 = 31610348
151 + 31610197 = 31610348
241 + 31610107 = 31610348
337 + 31610011 = 31610348
487 + 31609861 = 31610348
499 + 31609849 = 31610348

Showing the first eight; more decompositions exist.
