Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484122, here are decompositions:

29 + 31484093 = 31484122
41 + 31484081 = 31484122
53 + 31484069 = 31484122
233 + 31483889 = 31484122
239 + 31483883 = 31484122
251 + 31483871 = 31484122
281 + 31483841 = 31484122
389 + 31483733 = 31484122

Showing the first eight; more decompositions exist.
