Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467470, here are decompositions:

3 + 31467467 = 31467470
37 + 31467433 = 31467470
103 + 31467367 = 31467470
211 + 31467259 = 31467470
241 + 31467229 = 31467470
271 + 31467199 = 31467470
313 + 31467157 = 31467470
337 + 31467133 = 31467470

Showing the first eight; more decompositions exist.
