Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552, here are decompositions:

5 + 31547 = 31552
11 + 31541 = 31552
41 + 31511 = 31552
71 + 31481 = 31552
83 + 31469 = 31552
173 + 31379 = 31552
233 + 31319 = 31552
281 + 31271 = 31552

Showing the first eight; more decompositions exist.
