Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500696, here are decompositions:

5 + 31500691 = 31500696
37 + 31500659 = 31500696
47 + 31500649 = 31500696
107 + 31500589 = 31500696
127 + 31500569 = 31500696
137 + 31500559 = 31500696
167 + 31500529 = 31500696
193 + 31500503 = 31500696

Showing the first eight; more decompositions exist.
