Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599582, here are decompositions:

19 + 31599563 = 31599582
29 + 31599553 = 31599582
31 + 31599551 = 31599582
83 + 31599499 = 31599582
151 + 31599431 = 31599582
193 + 31599389 = 31599582
229 + 31599353 = 31599582
233 + 31599349 = 31599582

Showing the first eight; more decompositions exist.
