Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598724, here are decompositions:

7 + 31598717 = 31598724
23 + 31598701 = 31598724
37 + 31598687 = 31598724
41 + 31598683 = 31598724
181 + 31598543 = 31598724
211 + 31598513 = 31598724
307 + 31598417 = 31598724
347 + 31598377 = 31598724

Showing the first eight; more decompositions exist.
