Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588476, here are decompositions:

5 + 31588471 = 31588476
13 + 31588463 = 31588476
37 + 31588439 = 31588476
107 + 31588369 = 31588476
109 + 31588367 = 31588476
163 + 31588313 = 31588476
173 + 31588303 = 31588476
223 + 31588253 = 31588476

Showing the first eight; more decompositions exist.
