Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588910, here are decompositions:

13 + 31588897 = 31588910
97 + 31588813 = 31588910
103 + 31588807 = 31588910
211 + 31588699 = 31588910
307 + 31588603 = 31588910
349 + 31588561 = 31588910
439 + 31588471 = 31588910
541 + 31588369 = 31588910

Showing the first eight; more decompositions exist.
