Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588396, here are decompositions:

29 + 31588367 = 31588396
83 + 31588313 = 31588396
89 + 31588307 = 31588396
149 + 31588247 = 31588396
197 + 31588199 = 31588396
239 + 31588157 = 31588396
293 + 31588103 = 31588396
503 + 31587893 = 31588396

Showing the first eight; more decompositions exist.
