Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599130, here are decompositions:

29 + 31599101 = 31599130
71 + 31599059 = 31599130
191 + 31598939 = 31599130
197 + 31598933 = 31599130
257 + 31598873 = 31599130
263 + 31598867 = 31599130
347 + 31598783 = 31599130
359 + 31598771 = 31599130

Showing the first eight; more decompositions exist.
