Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598710, here are decompositions:

23 + 31598687 = 31598710
41 + 31598669 = 31598710
167 + 31598543 = 31598710
173 + 31598537 = 31598710
191 + 31598519 = 31598710
197 + 31598513 = 31598710
251 + 31598459 = 31598710
293 + 31598417 = 31598710

Showing the first eight; more decompositions exist.
