Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598560, here are decompositions:

17 + 31598543 = 31598560
23 + 31598537 = 31598560
41 + 31598519 = 31598560
47 + 31598513 = 31598560
101 + 31598459 = 31598560
137 + 31598423 = 31598560
179 + 31598381 = 31598560
197 + 31598363 = 31598560

Showing the first eight; more decompositions exist.
