Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588824, here are decompositions:

11 + 31588813 = 31588824
17 + 31588807 = 31588824
131 + 31588693 = 31588824
151 + 31588673 = 31588824
167 + 31588657 = 31588824
181 + 31588643 = 31588824
193 + 31588631 = 31588824
263 + 31588561 = 31588824

Showing the first eight; more decompositions exist.
