Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599858, here are decompositions:

47 + 31599811 = 31599858
97 + 31599761 = 31599858
131 + 31599727 = 31599858
151 + 31599707 = 31599858
229 + 31599629 = 31599858
307 + 31599551 = 31599858
359 + 31599499 = 31599858
419 + 31599439 = 31599858

Showing the first eight; more decompositions exist.
