Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462150, here are decompositions:

17 + 31462133 = 31462150
23 + 31462127 = 31462150
47 + 31462103 = 31462150
173 + 31461977 = 31462150
227 + 31461923 = 31462150
257 + 31461893 = 31462150
263 + 31461887 = 31462150
359 + 31461791 = 31462150

Showing the first eight; more decompositions exist.
