Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470794, here are decompositions:

7 + 31470787 = 31470794
13 + 31470781 = 31470794
73 + 31470721 = 31470794
457 + 31470337 = 31470794
571 + 31470223 = 31470794
577 + 31470217 = 31470794
601 + 31470193 = 31470794
643 + 31470151 = 31470794

Showing the first eight; more decompositions exist.
