Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588344, here are decompositions:

13 + 31588331 = 31588344
23 + 31588321 = 31588344
31 + 31588313 = 31588344
37 + 31588307 = 31588344
41 + 31588303 = 31588344
97 + 31588247 = 31588344
173 + 31588171 = 31588344
241 + 31588103 = 31588344

Showing the first eight; more decompositions exist.
