Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588296, here are decompositions:

29 + 31588267 = 31588296
43 + 31588253 = 31588296
97 + 31588199 = 31588296
139 + 31588157 = 31588296
167 + 31588129 = 31588296
193 + 31588103 = 31588296
277 + 31588019 = 31588296
293 + 31588003 = 31588296

Showing the first eight; more decompositions exist.
