Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599196, here are decompositions:

3 + 31599193 = 31599196
23 + 31599173 = 31599196
137 + 31599059 = 31599196
257 + 31598939 = 31599196
263 + 31598933 = 31599196
269 + 31598927 = 31599196
443 + 31598753 = 31599196
479 + 31598717 = 31599196

Showing the first eight; more decompositions exist.
