Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467190, here are decompositions:

23 + 31467167 = 31467190
101 + 31467089 = 31467190
107 + 31467083 = 31467190
179 + 31467011 = 31467190
191 + 31466999 = 31467190
197 + 31466993 = 31467190
239 + 31466951 = 31467190
257 + 31466933 = 31467190

Showing the first eight; more decompositions exist.
