Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608542, here are decompositions:

13 + 31608529 = 31608542
61 + 31608481 = 31608542
193 + 31608349 = 31608542
223 + 31608319 = 31608542
241 + 31608301 = 31608542
271 + 31608271 = 31608542
373 + 31608169 = 31608542
379 + 31608163 = 31608542

Showing the first eight; more decompositions exist.
