Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588354, here are decompositions:

3 + 31588351 = 31588354
23 + 31588331 = 31588354
41 + 31588313 = 31588354
47 + 31588307 = 31588354
101 + 31588253 = 31588354
107 + 31588247 = 31588354
197 + 31588157 = 31588354
251 + 31588103 = 31588354

Showing the first eight; more decompositions exist.
