Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467166, here are decompositions:

83 + 31467083 = 31467166
167 + 31466999 = 31467166
173 + 31466993 = 31467166
197 + 31466969 = 31467166
233 + 31466933 = 31467166
293 + 31466873 = 31467166
317 + 31466849 = 31467166
509 + 31466657 = 31467166

Showing the first eight; more decompositions exist.
