Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608608, here are decompositions:

19 + 31608589 = 31608608
79 + 31608529 = 31608608
127 + 31608481 = 31608608
181 + 31608427 = 31608608
271 + 31608337 = 31608608
307 + 31608301 = 31608608
337 + 31608271 = 31608608
439 + 31608169 = 31608608

Showing the first eight; more decompositions exist.
