Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598644, here are decompositions:

53 + 31598591 = 31598644
101 + 31598543 = 31598644
107 + 31598537 = 31598644
131 + 31598513 = 31598644
227 + 31598417 = 31598644
263 + 31598381 = 31598644
281 + 31598363 = 31598644
317 + 31598327 = 31598644

Showing the first eight; more decompositions exist.
