Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536460, here are decompositions:

101 + 31536359 = 31536460
107 + 31536353 = 31536460
113 + 31536347 = 31536460
167 + 31536293 = 31536460
173 + 31536287 = 31536460
233 + 31536227 = 31536460
257 + 31536203 = 31536460
359 + 31536101 = 31536460

Showing the first eight; more decompositions exist.
