Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462212, here are decompositions:

71 + 31462141 = 31462212
79 + 31462133 = 31462212
109 + 31462103 = 31462212
191 + 31462021 = 31462212
233 + 31461979 = 31462212
251 + 31461961 = 31462212
263 + 31461949 = 31462212
269 + 31461943 = 31462212

Showing the first eight; more decompositions exist.
