Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605598, here are decompositions:

5 + 31605593 = 31605598
41 + 31605557 = 31605598
47 + 31605551 = 31605598
107 + 31605491 = 31605598
179 + 31605419 = 31605598
191 + 31605407 = 31605598
197 + 31605401 = 31605598
359 + 31605239 = 31605598

Showing the first eight; more decompositions exist.
