Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598428, here are decompositions:

5 + 31598423 = 31598428
11 + 31598417 = 31598428
47 + 31598381 = 31598428
101 + 31598327 = 31598428
107 + 31598321 = 31598428
149 + 31598279 = 31598428
167 + 31598261 = 31598428
227 + 31598201 = 31598428

Showing the first eight; more decompositions exist.
