Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568222, here are decompositions:

19 + 31568203 = 31568222
43 + 31568179 = 31568222
139 + 31568083 = 31568222
151 + 31568071 = 31568222
163 + 31568059 = 31568222
181 + 31568041 = 31568222
223 + 31567999 = 31568222
241 + 31567981 = 31568222

Showing the first eight; more decompositions exist.
