Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467828, here are decompositions:

17 + 31467811 = 31467828
19 + 31467809 = 31467828
61 + 31467767 = 31467828
101 + 31467727 = 31467828
107 + 31467721 = 31467828
109 + 31467719 = 31467828
137 + 31467691 = 31467828
151 + 31467677 = 31467828

Showing the first eight; more decompositions exist.
