Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588516, here are decompositions:

23 + 31588493 = 31588516
53 + 31588463 = 31588516
149 + 31588367 = 31588516
263 + 31588253 = 31588516
269 + 31588247 = 31588516
317 + 31588199 = 31588516
359 + 31588157 = 31588516
593 + 31587923 = 31588516

Showing the first eight; more decompositions exist.
