Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598384, here are decompositions:

3 + 31598381 = 31598384
7 + 31598377 = 31598384
31 + 31598353 = 31598384
157 + 31598227 = 31598384
193 + 31598191 = 31598384
241 + 31598143 = 31598384
283 + 31598101 = 31598384
373 + 31598011 = 31598384

Showing the first eight; more decompositions exist.
