Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535208, here are decompositions:

37 + 31535171 = 31535208
101 + 31535107 = 31535208
127 + 31535081 = 31535208
149 + 31535059 = 31535208
151 + 31535057 = 31535208
197 + 31535011 = 31535208
227 + 31534981 = 31535208
337 + 31534871 = 31535208

Showing the first eight; more decompositions exist.
