Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474704, here are decompositions:

11 + 31474693 = 31474704
13 + 31474691 = 31474704
17 + 31474687 = 31474704
31 + 31474673 = 31474704
103 + 31474601 = 31474704
127 + 31474577 = 31474704
223 + 31474481 = 31474704
271 + 31474433 = 31474704

Showing the first eight; more decompositions exist.
