Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599258, here are decompositions:

11 + 31599247 = 31599258
101 + 31599157 = 31599258
157 + 31599101 = 31599258
199 + 31599059 = 31599258
269 + 31598989 = 31599258
311 + 31598947 = 31599258
331 + 31598927 = 31599258
347 + 31598911 = 31599258

Showing the first eight; more decompositions exist.
