Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535106, here are decompositions:

23 + 31535083 = 31535106
47 + 31535059 = 31535106
73 + 31535033 = 31535106
107 + 31534999 = 31535106
193 + 31534913 = 31535106
227 + 31534879 = 31535106
233 + 31534873 = 31535106
307 + 31534799 = 31535106

Showing the first eight; more decompositions exist.
