Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556022, here are decompositions:

11 + 31556011 = 31556022
23 + 31555999 = 31556022
31 + 31555991 = 31556022
41 + 31555981 = 31556022
53 + 31555969 = 31556022
73 + 31555949 = 31556022
83 + 31555939 = 31556022
89 + 31555933 = 31556022

Showing the first eight; more decompositions exist.
