Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596200, here are decompositions:

7 + 31596193 = 31596200
37 + 31596163 = 31596200
73 + 31596127 = 31596200
79 + 31596121 = 31596200
151 + 31596049 = 31596200
193 + 31596007 = 31596200
211 + 31595989 = 31596200
271 + 31595929 = 31596200

Showing the first eight; more decompositions exist.
