Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484136, here are decompositions:

7 + 31484129 = 31484136
43 + 31484093 = 31484136
67 + 31484069 = 31484136
157 + 31483979 = 31484136
179 + 31483957 = 31484136
223 + 31483913 = 31484136
317 + 31483819 = 31484136
337 + 31483799 = 31484136

Showing the first eight; more decompositions exist.
