Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454970, here are decompositions:

13 + 31454957 = 31454970
17 + 31454953 = 31454970
47 + 31454923 = 31454970
61 + 31454909 = 31454970
67 + 31454903 = 31454970
89 + 31454881 = 31454970
97 + 31454873 = 31454970
103 + 31454867 = 31454970

Showing the first eight; more decompositions exist.
