Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467172, here are decompositions:

3 + 31467169 = 31467172
5 + 31467167 = 31467172
83 + 31467089 = 31467172
89 + 31467083 = 31467172
101 + 31467071 = 31467172
173 + 31466999 = 31467172
179 + 31466993 = 31467172
239 + 31466933 = 31467172

Showing the first eight; more decompositions exist.
