Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535332, here are decompositions:

5 + 31535327 = 31535332
11 + 31535321 = 31535332
113 + 31535219 = 31535332
149 + 31535183 = 31535332
251 + 31535081 = 31535332
419 + 31534913 = 31535332
461 + 31534871 = 31535332
593 + 31534739 = 31535332

Showing the first eight; more decompositions exist.
