Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548532, here are decompositions:

5 + 31548527 = 31548532
11 + 31548521 = 31548532
89 + 31548443 = 31548532
101 + 31548431 = 31548532
131 + 31548401 = 31548532
233 + 31548299 = 31548532
251 + 31548281 = 31548532
263 + 31548269 = 31548532

Showing the first eight; more decompositions exist.
