Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548562, here are decompositions:

11 + 31548551 = 31548562
29 + 31548533 = 31548562
41 + 31548521 = 31548562
131 + 31548431 = 31548562
239 + 31548323 = 31548562
263 + 31548299 = 31548562
281 + 31548281 = 31548562
293 + 31548269 = 31548562

Showing the first eight; more decompositions exist.
