Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508114, here are decompositions:

7 + 31508107 = 31508114
13 + 31508101 = 31508114
31 + 31508083 = 31508114
37 + 31508077 = 31508114
97 + 31508017 = 31508114
163 + 31507951 = 31508114
193 + 31507921 = 31508114
277 + 31507837 = 31508114

Showing the first eight; more decompositions exist.
