Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467906, here are decompositions:

7 + 31467899 = 31467906
13 + 31467893 = 31467906
53 + 31467853 = 31467906
59 + 31467847 = 31467906
97 + 31467809 = 31467906
139 + 31467767 = 31467906
179 + 31467727 = 31467906
229 + 31467677 = 31467906

Showing the first eight; more decompositions exist.
