Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484152, here are decompositions:

23 + 31484129 = 31484152
59 + 31484093 = 31484152
71 + 31484081 = 31484152
83 + 31484069 = 31484152
173 + 31483979 = 31484152
233 + 31483919 = 31484152
239 + 31483913 = 31484152
263 + 31483889 = 31484152

Showing the first eight; more decompositions exist.
