Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598734, here are decompositions:

17 + 31598717 = 31598734
47 + 31598687 = 31598734
191 + 31598543 = 31598734
197 + 31598537 = 31598734
311 + 31598423 = 31598734
317 + 31598417 = 31598734
353 + 31598381 = 31598734
467 + 31598267 = 31598734

Showing the first eight; more decompositions exist.
