Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467464, here are decompositions:

31 + 31467433 = 31467464
97 + 31467367 = 31467464
163 + 31467301 = 31467464
283 + 31467181 = 31467464
307 + 31467157 = 31467464
331 + 31467133 = 31467464
337 + 31467127 = 31467464
397 + 31467067 = 31467464

Showing the first eight; more decompositions exist.
