Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467320, here are decompositions:

19 + 31467301 = 31467320
61 + 31467259 = 31467320
139 + 31467181 = 31467320
151 + 31467169 = 31467320
163 + 31467157 = 31467320
193 + 31467127 = 31467320
331 + 31466989 = 31467320
421 + 31466899 = 31467320

Showing the first eight; more decompositions exist.
