Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599628, here are decompositions:

17 + 31599611 = 31599628
29 + 31599599 = 31599628
197 + 31599431 = 31599628
239 + 31599389 = 31599628
569 + 31599059 = 31599628
701 + 31598927 = 31599628
719 + 31598909 = 31599628
761 + 31598867 = 31599628

Showing the first eight; more decompositions exist.
