Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556058, here are decompositions:

47 + 31556011 = 31556058
59 + 31555999 = 31556058
67 + 31555991 = 31556058
89 + 31555969 = 31556058
101 + 31555957 = 31556058
109 + 31555949 = 31556058
137 + 31555921 = 31556058
151 + 31555907 = 31556058

Showing the first eight; more decompositions exist.
