Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596558, here are decompositions:

5 + 31596553 = 31596558
17 + 31596541 = 31596558
47 + 31596511 = 31596558
61 + 31596497 = 31596558
139 + 31596419 = 31596558
157 + 31596401 = 31596558
167 + 31596391 = 31596558
179 + 31596379 = 31596558

Showing the first eight; more decompositions exist.
