Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606824, here are decompositions:

13 + 31606811 = 31606824
71 + 31606753 = 31606824
83 + 31606741 = 31606824
97 + 31606727 = 31606824
113 + 31606711 = 31606824
127 + 31606697 = 31606824
157 + 31606667 = 31606824
163 + 31606661 = 31606824

Showing the first eight; more decompositions exist.
