Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462166, here are decompositions:

97 + 31462069 = 31462166
163 + 31462003 = 31462166
223 + 31461943 = 31462166
349 + 31461817 = 31462166
613 + 31461553 = 31462166
643 + 31461523 = 31462166
709 + 31461457 = 31462166
739 + 31461427 = 31462166

Showing the first eight; more decompositions exist.
