Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462130, here are decompositions:

3 + 31462127 = 31462130
61 + 31462069 = 31462130
109 + 31462021 = 31462130
127 + 31462003 = 31462130
151 + 31461979 = 31462130
181 + 31461949 = 31462130
211 + 31461919 = 31462130
307 + 31461823 = 31462130

Showing the first eight; more decompositions exist.
