Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599532, here are decompositions:

101 + 31599431 = 31599532
179 + 31599353 = 31599532
191 + 31599341 = 31599532
359 + 31599173 = 31599532
431 + 31599101 = 31599532
593 + 31598939 = 31599532
599 + 31598933 = 31599532
659 + 31598873 = 31599532

Showing the first eight; more decompositions exist.
