Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536408, here are decompositions:

5 + 31536403 = 31536408
11 + 31536397 = 31536408
17 + 31536391 = 31536408
47 + 31536361 = 31536408
61 + 31536347 = 31536408
181 + 31536227 = 31536408
307 + 31536101 = 31536408
311 + 31536097 = 31536408

Showing the first eight; more decompositions exist.
