Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477922, here are decompositions:

43 + 31477879 = 31477922
163 + 31477759 = 31477922
193 + 31477729 = 31477922
199 + 31477723 = 31477922
211 + 31477711 = 31477922
373 + 31477549 = 31477922
379 + 31477543 = 31477922
409 + 31477513 = 31477922

Showing the first eight; more decompositions exist.
