Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462188, here are decompositions:

47 + 31462141 = 31462188
61 + 31462127 = 31462188
167 + 31462021 = 31462188
181 + 31462007 = 31462188
211 + 31461977 = 31462188
227 + 31461961 = 31462188
239 + 31461949 = 31462188
269 + 31461919 = 31462188

Showing the first eight; more decompositions exist.
