Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622808, here are decompositions:

5 + 31622803 = 31622808
29 + 31622779 = 31622808
31 + 31622777 = 31622808
67 + 31622741 = 31622808
79 + 31622729 = 31622808
109 + 31622699 = 31622808
137 + 31622671 = 31622808
167 + 31622641 = 31622808

Showing the first eight; more decompositions exist.
