Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462158, here are decompositions:

17 + 31462141 = 31462158
31 + 31462127 = 31462158
89 + 31462069 = 31462158
137 + 31462021 = 31462158
151 + 31462007 = 31462158
179 + 31461979 = 31462158
181 + 31461977 = 31462158
197 + 31461961 = 31462158

Showing the first eight; more decompositions exist.
