Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599016, here are decompositions:

83 + 31598933 = 31599016
89 + 31598927 = 31599016
107 + 31598909 = 31599016
149 + 31598867 = 31599016
227 + 31598789 = 31599016
233 + 31598783 = 31599016
263 + 31598753 = 31599016
347 + 31598669 = 31599016

Showing the first eight; more decompositions exist.
