Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462122, here are decompositions:

19 + 31462103 = 31462122
53 + 31462069 = 31462122
101 + 31462021 = 31462122
173 + 31461949 = 31462122
179 + 31461943 = 31462122
199 + 31461923 = 31462122
229 + 31461893 = 31462122
271 + 31461851 = 31462122

Showing the first eight; more decompositions exist.
