Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535410, here are decompositions:

29 + 31535381 = 31535410
83 + 31535327 = 31535410
89 + 31535321 = 31535410
191 + 31535219 = 31535410
197 + 31535213 = 31535410
227 + 31535183 = 31535410
239 + 31535171 = 31535410
353 + 31535057 = 31535410

Showing the first eight; more decompositions exist.
