Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467930, here are decompositions:

19 + 31467911 = 31467930
31 + 31467899 = 31467930
37 + 31467893 = 31467930
83 + 31467847 = 31467930
101 + 31467829 = 31467930
163 + 31467767 = 31467930
167 + 31467763 = 31467930
211 + 31467719 = 31467930

Showing the first eight; more decompositions exist.
