Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588836, here are decompositions:

23 + 31588813 = 31588836
29 + 31588807 = 31588836
127 + 31588709 = 31588836
137 + 31588699 = 31588836
157 + 31588679 = 31588836
163 + 31588673 = 31588836
179 + 31588657 = 31588836
193 + 31588643 = 31588836

Showing the first eight; more decompositions exist.
