Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462160, here are decompositions:

19 + 31462141 = 31462160
139 + 31462021 = 31462160
157 + 31462003 = 31462160
181 + 31461979 = 31462160
199 + 31461961 = 31462160
211 + 31461949 = 31462160
241 + 31461919 = 31462160
337 + 31461823 = 31462160

Showing the first eight; more decompositions exist.
