Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588964, here are decompositions:

7 + 31588957 = 31588964
13 + 31588951 = 31588964
31 + 31588933 = 31588964
37 + 31588927 = 31588964
67 + 31588897 = 31588964
151 + 31588813 = 31588964
157 + 31588807 = 31588964
271 + 31588693 = 31588964

Showing the first eight; more decompositions exist.
