Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505696, here are decompositions:

3 + 31505693 = 31505696
37 + 31505659 = 31505696
73 + 31505623 = 31505696
97 + 31505599 = 31505696
127 + 31505569 = 31505696
163 + 31505533 = 31505696
223 + 31505473 = 31505696
337 + 31505359 = 31505696

Showing the first eight; more decompositions exist.
