Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608504, here are decompositions:

7 + 31608497 = 31608504
23 + 31608481 = 31608504
163 + 31608341 = 31608504
167 + 31608337 = 31608504
233 + 31608271 = 31608504
241 + 31608263 = 31608504
337 + 31608167 = 31608504
373 + 31608131 = 31608504

Showing the first eight; more decompositions exist.
