Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535266, here are decompositions:

3 + 31535263 = 31535266
47 + 31535219 = 31535266
53 + 31535213 = 31535266
83 + 31535183 = 31535266
233 + 31535033 = 31535266
353 + 31534913 = 31535266
467 + 31534799 = 31535266
479 + 31534787 = 31535266

Showing the first eight; more decompositions exist.
