Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535334, here are decompositions:

7 + 31535327 = 31535334
13 + 31535321 = 31535334
23 + 31535311 = 31535334
71 + 31535263 = 31535334
101 + 31535233 = 31535334
107 + 31535227 = 31535334
151 + 31535183 = 31535334
163 + 31535171 = 31535334

Showing the first eight; more decompositions exist.
