Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467164, here are decompositions:

7 + 31467157 = 31467164
31 + 31467133 = 31467164
37 + 31467127 = 31467164
61 + 31467103 = 31467164
97 + 31467067 = 31467164
271 + 31466893 = 31467164
307 + 31466857 = 31467164
373 + 31466791 = 31467164

Showing the first eight; more decompositions exist.
