Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608534, here are decompositions:

5 + 31608529 = 31608534
7 + 31608527 = 31608534
37 + 31608497 = 31608534
53 + 31608481 = 31608534
107 + 31608427 = 31608534
193 + 31608341 = 31608534
197 + 31608337 = 31608534
233 + 31608301 = 31608534

Showing the first eight; more decompositions exist.
