Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598476, here are decompositions:

17 + 31598459 = 31598476
53 + 31598423 = 31598476
59 + 31598417 = 31598476
113 + 31598363 = 31598476
149 + 31598327 = 31598476
197 + 31598279 = 31598476
263 + 31598213 = 31598476
419 + 31598057 = 31598476

Showing the first eight; more decompositions exist.
