Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608946, here are decompositions:

29 + 31608917 = 31608946
53 + 31608893 = 31608946
59 + 31608887 = 31608946
167 + 31608779 = 31608946
197 + 31608749 = 31608946
233 + 31608713 = 31608946
359 + 31608587 = 31608946
419 + 31608527 = 31608946

Showing the first eight; more decompositions exist.
