Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599666, here are decompositions:

13 + 31599653 = 31599666
17 + 31599649 = 31599666
37 + 31599629 = 31599666
67 + 31599599 = 31599666
103 + 31599563 = 31599666
113 + 31599553 = 31599666
167 + 31599499 = 31599666
179 + 31599487 = 31599666

Showing the first eight; more decompositions exist.
