Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462156, here are decompositions:

23 + 31462133 = 31462156
29 + 31462127 = 31462156
53 + 31462103 = 31462156
149 + 31462007 = 31462156
179 + 31461977 = 31462156
233 + 31461923 = 31462156
263 + 31461893 = 31462156
269 + 31461887 = 31462156

Showing the first eight; more decompositions exist.
