Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556034, here are decompositions:

23 + 31556011 = 31556034
43 + 31555991 = 31556034
53 + 31555981 = 31556034
67 + 31555967 = 31556034
101 + 31555933 = 31556034
113 + 31555921 = 31556034
127 + 31555907 = 31556034
157 + 31555877 = 31556034

Showing the first eight; more decompositions exist.
