Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535110, here are decompositions:

3 + 31535107 = 31535110
29 + 31535081 = 31535110
53 + 31535057 = 31535110
149 + 31534961 = 31535110
197 + 31534913 = 31535110
239 + 31534871 = 31535110
311 + 31534799 = 31535110
353 + 31534757 = 31535110

Showing the first eight; more decompositions exist.
