Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467200, here are decompositions:

19 + 31467181 = 31467200
31 + 31467169 = 31467200
43 + 31467157 = 31467200
67 + 31467133 = 31467200
73 + 31467127 = 31467200
97 + 31467103 = 31467200
211 + 31466989 = 31467200
223 + 31466977 = 31467200

Showing the first eight; more decompositions exist.
