Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535306, here are decompositions:

43 + 31535263 = 31535306
73 + 31535233 = 31535306
79 + 31535227 = 31535306
163 + 31535143 = 31535306
193 + 31535113 = 31535306
199 + 31535107 = 31535306
223 + 31535083 = 31535306
307 + 31534999 = 31535306

Showing the first eight; more decompositions exist.
