Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596100, here are decompositions:

59 + 31596041 = 31596100
71 + 31596029 = 31596100
131 + 31595969 = 31596100
227 + 31595873 = 31596100
233 + 31595867 = 31596100
269 + 31595831 = 31596100
293 + 31595807 = 31596100
317 + 31595783 = 31596100

Showing the first eight; more decompositions exist.
