Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598368, here are decompositions:

5 + 31598363 = 31598368
41 + 31598327 = 31598368
47 + 31598321 = 31598368
89 + 31598279 = 31598368
101 + 31598267 = 31598368
107 + 31598261 = 31598368
167 + 31598201 = 31598368
227 + 31598141 = 31598368

Showing the first eight; more decompositions exist.
