Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596872, here are decompositions:

79 + 31596793 = 31596872
103 + 31596769 = 31596872
163 + 31596709 = 31596872
193 + 31596679 = 31596872
199 + 31596673 = 31596872
211 + 31596661 = 31596872
331 + 31596541 = 31596872
709 + 31596163 = 31596872

Showing the first eight; more decompositions exist.
