Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477934, here are decompositions:

181 + 31477753 = 31477934
211 + 31477723 = 31477934
223 + 31477711 = 31477934
277 + 31477657 = 31477934
331 + 31477603 = 31477934
373 + 31477561 = 31477934
421 + 31477513 = 31477934
487 + 31477447 = 31477934

Showing the first eight; more decompositions exist.
