Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588962, here are decompositions:

5 + 31588957 = 31588962
11 + 31588951 = 31588962
19 + 31588943 = 31588962
29 + 31588933 = 31588962
149 + 31588813 = 31588962
263 + 31588699 = 31588962
269 + 31588693 = 31588962
283 + 31588679 = 31588962

Showing the first eight; more decompositions exist.
