Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556106, here are decompositions:

7 + 31556099 = 31556106
73 + 31556033 = 31556106
107 + 31555999 = 31556106
137 + 31555969 = 31556106
139 + 31555967 = 31556106
149 + 31555957 = 31556106
157 + 31555949 = 31556106
167 + 31555939 = 31556106

Showing the first eight; more decompositions exist.
