Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599126, here are decompositions:

23 + 31599103 = 31599126
67 + 31599059 = 31599126
137 + 31598989 = 31599126
173 + 31598953 = 31599126
179 + 31598947 = 31599126
193 + 31598933 = 31599126
199 + 31598927 = 31599126
239 + 31598887 = 31599126

Showing the first eight; more decompositions exist.
