Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556074, here are decompositions:

41 + 31556033 = 31556074
83 + 31555991 = 31556074
107 + 31555967 = 31556074
167 + 31555907 = 31556074
197 + 31555877 = 31556074
233 + 31555841 = 31556074
293 + 31555781 = 31556074
311 + 31555763 = 31556074

Showing the first eight; more decompositions exist.
