Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599222, here are decompositions:

29 + 31599193 = 31599222
163 + 31599059 = 31599222
233 + 31598989 = 31599222
269 + 31598953 = 31599222
283 + 31598939 = 31599222
311 + 31598911 = 31599222
313 + 31598909 = 31599222
349 + 31598873 = 31599222

Showing the first eight; more decompositions exist.
