Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588956, here are decompositions:

5 + 31588951 = 31588956
13 + 31588943 = 31588956
23 + 31588933 = 31588956
29 + 31588927 = 31588956
59 + 31588897 = 31588956
109 + 31588847 = 31588956
149 + 31588807 = 31588956
257 + 31588699 = 31588956

Showing the first eight; more decompositions exist.
