Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468162, here are decompositions:

3 + 31468159 = 31468162
149 + 31468013 = 31468162
179 + 31467983 = 31468162
251 + 31467911 = 31468162
263 + 31467899 = 31468162
269 + 31467893 = 31468162
353 + 31467809 = 31468162
443 + 31467719 = 31468162

Showing the first eight; more decompositions exist.
