Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556054, here are decompositions:

43 + 31556011 = 31556054
73 + 31555981 = 31556054
97 + 31555957 = 31556054
163 + 31555891 = 31556054
181 + 31555873 = 31556054
241 + 31555813 = 31556054
337 + 31555717 = 31556054
421 + 31555633 = 31556054

Showing the first eight; more decompositions exist.
