Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599266, here are decompositions:

7 + 31599259 = 31599266
19 + 31599247 = 31599266
73 + 31599193 = 31599266
109 + 31599157 = 31599266
163 + 31599103 = 31599266
277 + 31598989 = 31599266
313 + 31598953 = 31599266
379 + 31598887 = 31599266

Showing the first eight; more decompositions exist.
