Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467482, here are decompositions:

181 + 31467301 = 31467482
223 + 31467259 = 31467482
283 + 31467199 = 31467482
313 + 31467169 = 31467482
349 + 31467133 = 31467482
379 + 31467103 = 31467482
661 + 31466821 = 31467482
691 + 31466791 = 31467482

Showing the first eight; more decompositions exist.
