Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599534, here are decompositions:

47 + 31599487 = 31599534
103 + 31599431 = 31599534
181 + 31599353 = 31599534
193 + 31599341 = 31599534
227 + 31599307 = 31599534
431 + 31599103 = 31599534
433 + 31599101 = 31599534
587 + 31598947 = 31599534

Showing the first eight; more decompositions exist.
