Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454108, here are decompositions:

31 + 31454077 = 31454108
139 + 31453969 = 31454108
151 + 31453957 = 31454108
199 + 31453909 = 31454108
211 + 31453897 = 31454108
229 + 31453879 = 31454108
241 + 31453867 = 31454108
397 + 31453711 = 31454108

Showing the first eight; more decompositions exist.
