Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559334, here are decompositions:

13 + 31559321 = 31559334
17 + 31559317 = 31559334
71 + 31559263 = 31559334
83 + 31559251 = 31559334
127 + 31559207 = 31559334
173 + 31559161 = 31559334
241 + 31559093 = 31559334
263 + 31559071 = 31559334

Showing the first eight; more decompositions exist.
