Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588536, here are decompositions:

13 + 31588523 = 31588536
43 + 31588493 = 31588536
53 + 31588483 = 31588536
73 + 31588463 = 31588536
97 + 31588439 = 31588536
137 + 31588399 = 31588536
167 + 31588369 = 31588536
179 + 31588357 = 31588536

Showing the first eight; more decompositions exist.
