Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628296, here are decompositions:

5 + 31628291 = 31628296
23 + 31628273 = 31628296
47 + 31628249 = 31628296
197 + 31628099 = 31628296
317 + 31627979 = 31628296
347 + 31627949 = 31628296
503 + 31627793 = 31628296
569 + 31627727 = 31628296

Showing the first eight; more decompositions exist.
