Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536468, here are decompositions:

71 + 31536397 = 31536468
107 + 31536361 = 31536468
109 + 31536359 = 31536468
181 + 31536287 = 31536468
241 + 31536227 = 31536468
281 + 31536187 = 31536468
307 + 31536161 = 31536468
367 + 31536101 = 31536468

Showing the first eight; more decompositions exist.
