Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471862, here are decompositions:

13 + 31471849 = 31471862
31 + 31471831 = 31471862
151 + 31471711 = 31471862
181 + 31471681 = 31471862
199 + 31471663 = 31471862
223 + 31471639 = 31471862
229 + 31471633 = 31471862
241 + 31471621 = 31471862

Showing the first eight; more decompositions exist.
