Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598674, here are decompositions:

5 + 31598669 = 31598674
83 + 31598591 = 31598674
131 + 31598543 = 31598674
137 + 31598537 = 31598674
251 + 31598423 = 31598674
257 + 31598417 = 31598674
293 + 31598381 = 31598674
311 + 31598363 = 31598674

Showing the first eight; more decompositions exist.
