Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605954, here are decompositions:

41 + 31605913 = 31605954
131 + 31605823 = 31605954
151 + 31605803 = 31605954
173 + 31605781 = 31605954
181 + 31605773 = 31605954
197 + 31605757 = 31605954
227 + 31605727 = 31605954
241 + 31605713 = 31605954

Showing the first eight; more decompositions exist.
