Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462106, here are decompositions:

3 + 31462103 = 31462106
37 + 31462069 = 31462106
103 + 31462003 = 31462106
127 + 31461979 = 31462106
157 + 31461949 = 31462106
163 + 31461943 = 31462106
283 + 31461823 = 31462106
409 + 31461697 = 31462106

Showing the first eight; more decompositions exist.
