Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529266, here are decompositions:

17 + 31529249 = 31529266
23 + 31529243 = 31529266
47 + 31529219 = 31529266
53 + 31529213 = 31529266
179 + 31529087 = 31529266
269 + 31528997 = 31529266
443 + 31528823 = 31529266
569 + 31528697 = 31529266

Showing the first eight; more decompositions exist.
