Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588860, here are decompositions:

13 + 31588847 = 31588860
47 + 31588813 = 31588860
53 + 31588807 = 31588860
151 + 31588709 = 31588860
167 + 31588693 = 31588860
181 + 31588679 = 31588860
229 + 31588631 = 31588860
257 + 31588603 = 31588860

Showing the first eight; more decompositions exist.
