Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468000, here are decompositions:

17 + 31467983 = 31468000
89 + 31467911 = 31468000
101 + 31467899 = 31468000
107 + 31467893 = 31468000
191 + 31467809 = 31468000
233 + 31467767 = 31468000
281 + 31467719 = 31468000
353 + 31467647 = 31468000

Showing the first eight; more decompositions exist.
