Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462110, here are decompositions:

7 + 31462103 = 31462110
41 + 31462069 = 31462110
89 + 31462021 = 31462110
103 + 31462007 = 31462110
107 + 31462003 = 31462110
131 + 31461979 = 31462110
149 + 31461961 = 31462110
167 + 31461943 = 31462110

Showing the first eight; more decompositions exist.
