Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598506, here are decompositions:

47 + 31598459 = 31598506
83 + 31598423 = 31598506
89 + 31598417 = 31598506
179 + 31598327 = 31598506
227 + 31598279 = 31598506
239 + 31598267 = 31598506
293 + 31598213 = 31598506
449 + 31598057 = 31598506

Showing the first eight; more decompositions exist.
