Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529256, here are decompositions:

7 + 31529249 = 31529256
13 + 31529243 = 31529256
37 + 31529219 = 31529256
43 + 31529213 = 31529256
89 + 31529167 = 31529256
107 + 31529149 = 31529256
149 + 31529107 = 31529256
167 + 31529089 = 31529256

Showing the first eight; more decompositions exist.
