Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470752, here are decompositions:

31 + 31470721 = 31470752
43 + 31470709 = 31470752
283 + 31470469 = 31470752
373 + 31470379 = 31470752
601 + 31470151 = 31470752
739 + 31470013 = 31470752
829 + 31469923 = 31470752
991 + 31469761 = 31470752

Showing the first eight; more decompositions exist.
