Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558296, here are decompositions:

13 + 31558283 = 31558296
43 + 31558253 = 31558296
67 + 31558229 = 31558296
73 + 31558223 = 31558296
89 + 31558207 = 31558296
97 + 31558199 = 31558296
109 + 31558187 = 31558296
127 + 31558169 = 31558296

Showing the first eight; more decompositions exist.
