Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468110, here are decompositions:

13 + 31468097 = 31468110
43 + 31468067 = 31468110
83 + 31468027 = 31468110
97 + 31468013 = 31468110
109 + 31468001 = 31468110
127 + 31467983 = 31468110
173 + 31467937 = 31468110
199 + 31467911 = 31468110

Showing the first eight; more decompositions exist.
