Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526256, here are decompositions:

17 + 31526239 = 31526256
29 + 31526227 = 31526256
43 + 31526213 = 31526256
59 + 31526197 = 31526256
67 + 31526189 = 31526256
173 + 31526083 = 31526256
193 + 31526063 = 31526256
199 + 31526057 = 31526256

Showing the first eight; more decompositions exist.
