Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536318, here are decompositions:

5 + 31536313 = 31536318
31 + 31536287 = 31536318
131 + 31536187 = 31536318
157 + 31536161 = 31536318
257 + 31536061 = 31536318
269 + 31536049 = 31536318
337 + 31535981 = 31536318
379 + 31535939 = 31536318

Showing the first eight; more decompositions exist.
