Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606982, here are decompositions:

3 + 31606979 = 31606982
19 + 31606963 = 31606982
31 + 31606951 = 31606982
79 + 31606903 = 31606982
103 + 31606879 = 31606982
229 + 31606753 = 31606982
241 + 31606741 = 31606982
271 + 31606711 = 31606982

Showing the first eight; more decompositions exist.
