Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598302, here are decompositions:

3 + 31598299 = 31598302
23 + 31598279 = 31598302
41 + 31598261 = 31598302
89 + 31598213 = 31598302
101 + 31598201 = 31598302
269 + 31598033 = 31598302
293 + 31598009 = 31598302
389 + 31597913 = 31598302

Showing the first eight; more decompositions exist.
