Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462982, here are decompositions:

3 + 31462979 = 31462982
13 + 31462969 = 31462982
73 + 31462909 = 31462982
151 + 31462831 = 31462982
211 + 31462771 = 31462982
223 + 31462759 = 31462982
373 + 31462609 = 31462982
379 + 31462603 = 31462982

Showing the first eight; more decompositions exist.
