Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622904, here are decompositions:

11 + 31622893 = 31622904
23 + 31622881 = 31622904
41 + 31622863 = 31622904
67 + 31622837 = 31622904
101 + 31622803 = 31622904
127 + 31622777 = 31622904
163 + 31622741 = 31622904
191 + 31622713 = 31622904

Showing the first eight; more decompositions exist.
