Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454934, here are decompositions:

11 + 31454923 = 31454934
31 + 31454903 = 31454934
53 + 31454881 = 31454934
61 + 31454873 = 31454934
67 + 31454867 = 31454934
97 + 31454837 = 31454934
107 + 31454827 = 31454934
151 + 31454783 = 31454934

Showing the first eight; more decompositions exist.
