Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598718, here are decompositions:

17 + 31598701 = 31598718
31 + 31598687 = 31598718
71 + 31598647 = 31598718
127 + 31598591 = 31598718
181 + 31598537 = 31598718
197 + 31598521 = 31598718
199 + 31598519 = 31598718
269 + 31598449 = 31598718

Showing the first eight; more decompositions exist.
