Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462146, here are decompositions:

5 + 31462141 = 31462146
13 + 31462133 = 31462146
19 + 31462127 = 31462146
43 + 31462103 = 31462146
139 + 31462007 = 31462146
167 + 31461979 = 31462146
197 + 31461949 = 31462146
223 + 31461923 = 31462146

Showing the first eight; more decompositions exist.
