Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588496, here are decompositions:

3 + 31588493 = 31588496
13 + 31588483 = 31588496
97 + 31588399 = 31588496
127 + 31588369 = 31588496
139 + 31588357 = 31588496
193 + 31588303 = 31588496
229 + 31588267 = 31588496
367 + 31588129 = 31588496

Showing the first eight; more decompositions exist.
