Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559346, here are decompositions:

29 + 31559317 = 31559346
83 + 31559263 = 31559346
107 + 31559239 = 31559346
127 + 31559219 = 31559346
139 + 31559207 = 31559346
157 + 31559189 = 31559346
197 + 31559149 = 31559346
277 + 31559069 = 31559346

Showing the first eight; more decompositions exist.
