Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531068, here are decompositions:

5 + 31531063 = 31531068
11 + 31531057 = 31531068
67 + 31531001 = 31531068
89 + 31530979 = 31531068
109 + 31530959 = 31531068
167 + 31530901 = 31531068
227 + 31530841 = 31531068
241 + 31530827 = 31531068

Showing the first eight; more decompositions exist.
