Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463000, here are decompositions:

31 + 31462969 = 31463000
67 + 31462933 = 31463000
103 + 31462897 = 31463000
193 + 31462807 = 31463000
229 + 31462771 = 31463000
241 + 31462759 = 31463000
271 + 31462729 = 31463000
277 + 31462723 = 31463000

Showing the first eight; more decompositions exist.
