Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608256, here are decompositions:

89 + 31608167 = 31608256
107 + 31608149 = 31608256
149 + 31608107 = 31608256
227 + 31608029 = 31608256
347 + 31607909 = 31608256
353 + 31607903 = 31608256
359 + 31607897 = 31608256
389 + 31607867 = 31608256

Showing the first eight; more decompositions exist.
