Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462266, here are decompositions:

139 + 31462127 = 31462266
163 + 31462103 = 31462266
197 + 31462069 = 31462266
263 + 31462003 = 31462266
317 + 31461949 = 31462266
347 + 31461919 = 31462266
373 + 31461893 = 31462266
379 + 31461887 = 31462266

Showing the first eight; more decompositions exist.
