Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599342, here are decompositions:

29 + 31599313 = 31599342
83 + 31599259 = 31599342
149 + 31599193 = 31599342
239 + 31599103 = 31599342
241 + 31599101 = 31599342
283 + 31599059 = 31599342
353 + 31598989 = 31599342
389 + 31598953 = 31599342

Showing the first eight; more decompositions exist.
