Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599664, here are decompositions:

11 + 31599653 = 31599664
53 + 31599611 = 31599664
101 + 31599563 = 31599664
113 + 31599551 = 31599664
233 + 31599431 = 31599664
311 + 31599353 = 31599664
491 + 31599173 = 31599664
563 + 31599101 = 31599664

Showing the first eight; more decompositions exist.
