Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535346, here are decompositions:

5 + 31535341 = 31535346
19 + 31535327 = 31535346
83 + 31535263 = 31535346
113 + 31535233 = 31535346
127 + 31535219 = 31535346
163 + 31535183 = 31535346
173 + 31535173 = 31535346
223 + 31535123 = 31535346

Showing the first eight; more decompositions exist.
