Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605944, here are decompositions:

31 + 31605913 = 31605944
67 + 31605877 = 31605944
163 + 31605781 = 31605944
367 + 31605577 = 31605944
373 + 31605571 = 31605944
673 + 31605271 = 31605944
1201 + 31604743 = 31605944
1213 + 31604731 = 31605944

Showing the first eight; more decompositions exist.
