Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475696, here are decompositions:

13 + 31475683 = 31475696
19 + 31475677 = 31475696
73 + 31475623 = 31475696
97 + 31475599 = 31475696
379 + 31475317 = 31475696
409 + 31475287 = 31475696
487 + 31475209 = 31475696
607 + 31475089 = 31475696

Showing the first eight; more decompositions exist.
