Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556576, here are decompositions:

19 + 31556557 = 31556576
97 + 31556479 = 31556576
109 + 31556467 = 31556576
223 + 31556353 = 31556576
283 + 31556293 = 31556576
433 + 31556143 = 31556576
463 + 31556113 = 31556576
577 + 31555999 = 31556576

Showing the first eight; more decompositions exist.
