Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599132, here are decompositions:

29 + 31599103 = 31599132
31 + 31599101 = 31599132
73 + 31599059 = 31599132
179 + 31598953 = 31599132
193 + 31598939 = 31599132
199 + 31598933 = 31599132
223 + 31598909 = 31599132
269 + 31598863 = 31599132

Showing the first eight; more decompositions exist.
