Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462164, here are decompositions:

23 + 31462141 = 31462164
31 + 31462133 = 31462164
37 + 31462127 = 31462164
61 + 31462103 = 31462164
157 + 31462007 = 31462164
241 + 31461923 = 31462164
271 + 31461893 = 31462164
277 + 31461887 = 31462164

Showing the first eight; more decompositions exist.
