Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484106, here are decompositions:

13 + 31484093 = 31484106
37 + 31484069 = 31484106
47 + 31484059 = 31484106
127 + 31483979 = 31484106
149 + 31483957 = 31484106
179 + 31483927 = 31484106
193 + 31483913 = 31484106
223 + 31483883 = 31484106

Showing the first eight; more decompositions exist.
