Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534968, here are decompositions:

7 + 31534961 = 31534968
89 + 31534879 = 31534968
97 + 31534871 = 31534968
137 + 31534831 = 31534968
149 + 31534819 = 31534968
167 + 31534801 = 31534968
181 + 31534787 = 31534968
211 + 31534757 = 31534968

Showing the first eight; more decompositions exist.
