Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598700, here are decompositions:

13 + 31598687 = 31598700
17 + 31598683 = 31598700
31 + 31598669 = 31598700
53 + 31598647 = 31598700
109 + 31598591 = 31598700
157 + 31598543 = 31598700
163 + 31598537 = 31598700
179 + 31598521 = 31598700

Showing the first eight; more decompositions exist.
