Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535350, here are decompositions:

23 + 31535327 = 31535350
29 + 31535321 = 31535350
131 + 31535219 = 31535350
137 + 31535213 = 31535350
167 + 31535183 = 31535350
179 + 31535171 = 31535350
227 + 31535123 = 31535350
269 + 31535081 = 31535350

Showing the first eight; more decompositions exist.
