Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462234, here are decompositions:

17 + 31462217 = 31462234
101 + 31462133 = 31462234
107 + 31462127 = 31462234
131 + 31462103 = 31462234
227 + 31462007 = 31462234
257 + 31461977 = 31462234
311 + 31461923 = 31462234
347 + 31461887 = 31462234

Showing the first eight; more decompositions exist.
