Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548556, here are decompositions:

5 + 31548551 = 31548556
23 + 31548533 = 31548556
29 + 31548527 = 31548556
89 + 31548467 = 31548556
113 + 31548443 = 31548556
233 + 31548323 = 31548556
257 + 31548299 = 31548556
269 + 31548287 = 31548556

Showing the first eight; more decompositions exist.
