Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467404, here are decompositions:

37 + 31467367 = 31467404
103 + 31467301 = 31467404
223 + 31467181 = 31467404
271 + 31467133 = 31467404
277 + 31467127 = 31467404
337 + 31467067 = 31467404
547 + 31466857 = 31467404
613 + 31466791 = 31467404

Showing the first eight; more decompositions exist.
