Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548534, here are decompositions:

7 + 31548527 = 31548534
13 + 31548521 = 31548534
67 + 31548467 = 31548534
103 + 31548431 = 31548534
107 + 31548427 = 31548534
191 + 31548343 = 31548534
211 + 31548323 = 31548534
233 + 31548301 = 31548534

Showing the first eight; more decompositions exist.
