Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534200, here are decompositions:

13 + 31534187 = 31534200
17 + 31534183 = 31534200
31 + 31534169 = 31534200
59 + 31534141 = 31534200
79 + 31534121 = 31534200
83 + 31534117 = 31534200
97 + 31534103 = 31534200
127 + 31534073 = 31534200

Showing the first eight; more decompositions exist.
