Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605794, here are decompositions:

13 + 31605781 = 31605794
37 + 31605757 = 31605794
67 + 31605727 = 31605794
97 + 31605697 = 31605794
211 + 31605583 = 31605794
223 + 31605571 = 31605794
277 + 31605517 = 31605794
433 + 31605361 = 31605794

Showing the first eight; more decompositions exist.
