Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556464, here are decompositions:

3 + 31556461 = 31556464
41 + 31556423 = 31556464
47 + 31556417 = 31556464
83 + 31556381 = 31556464
263 + 31556201 = 31556464
383 + 31556081 = 31556464
431 + 31556033 = 31556464
557 + 31555907 = 31556464

Showing the first eight; more decompositions exist.
