Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608184, here are decompositions:

17 + 31608167 = 31608184
53 + 31608131 = 31608184
137 + 31608047 = 31608184
263 + 31607921 = 31608184
281 + 31607903 = 31608184
317 + 31607867 = 31608184
353 + 31607831 = 31608184
401 + 31607783 = 31608184

Showing the first eight; more decompositions exist.
