Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600858, here are decompositions:

41 + 31600817 = 31600858
59 + 31600799 = 31600858
137 + 31600721 = 31600858
239 + 31600619 = 31600858
347 + 31600511 = 31600858
449 + 31600409 = 31600858
557 + 31600301 = 31600858
599 + 31600259 = 31600858

Showing the first eight; more decompositions exist.
