Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605834, here are decompositions:

11 + 31605823 = 31605834
23 + 31605811 = 31605834
31 + 31605803 = 31605834
53 + 31605781 = 31605834
61 + 31605773 = 31605834
107 + 31605727 = 31605834
137 + 31605697 = 31605834
241 + 31605593 = 31605834

Showing the first eight; more decompositions exist.
