Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467954, here are decompositions:

5 + 31467949 = 31467954
17 + 31467937 = 31467954
43 + 31467911 = 31467954
61 + 31467893 = 31467954
101 + 31467853 = 31467954
107 + 31467847 = 31467954
191 + 31467763 = 31467954
227 + 31467727 = 31467954

Showing the first eight; more decompositions exist.
