Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484196, here are decompositions:

17 + 31484179 = 31484196
19 + 31484177 = 31484196
53 + 31484143 = 31484196
67 + 31484129 = 31484196
103 + 31484093 = 31484196
127 + 31484069 = 31484196
137 + 31484059 = 31484196
239 + 31483957 = 31484196

Showing the first eight; more decompositions exist.
