Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596142, here are decompositions:

23 + 31596119 = 31596142
101 + 31596041 = 31596142
113 + 31596029 = 31596142
173 + 31595969 = 31596142
269 + 31595873 = 31596142
311 + 31595831 = 31596142
359 + 31595783 = 31596142
419 + 31595723 = 31596142

Showing the first eight; more decompositions exist.
