Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458162, here are decompositions:

31 + 31458131 = 31458162
79 + 31458083 = 31458162
101 + 31458061 = 31458162
149 + 31458013 = 31458162
163 + 31457999 = 31458162
173 + 31457989 = 31458162
193 + 31457969 = 31458162
233 + 31457929 = 31458162

Showing the first eight; more decompositions exist.
