Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608600, here are decompositions:

11 + 31608589 = 31608600
13 + 31608587 = 31608600
71 + 31608529 = 31608600
73 + 31608527 = 31608600
103 + 31608497 = 31608600
151 + 31608449 = 31608600
173 + 31608427 = 31608600
251 + 31608349 = 31608600

Showing the first eight; more decompositions exist.
