Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599934, here are decompositions:

5 + 31599929 = 31599934
17 + 31599917 = 31599934
167 + 31599767 = 31599934
173 + 31599761 = 31599934
227 + 31599707 = 31599934
251 + 31599683 = 31599934
263 + 31599671 = 31599934
281 + 31599653 = 31599934

Showing the first eight; more decompositions exist.
