Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598692, here are decompositions:

5 + 31598687 = 31598692
23 + 31598669 = 31598692
101 + 31598591 = 31598692
149 + 31598543 = 31598692
173 + 31598519 = 31598692
179 + 31598513 = 31598692
233 + 31598459 = 31598692
269 + 31598423 = 31598692

Showing the first eight; more decompositions exist.
