Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556088, here are decompositions:

7 + 31556081 = 31556088
89 + 31555999 = 31556088
97 + 31555991 = 31556088
107 + 31555981 = 31556088
131 + 31555957 = 31556088
139 + 31555949 = 31556088
149 + 31555939 = 31556088
167 + 31555921 = 31556088

Showing the first eight; more decompositions exist.
