Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535354, here are decompositions:

13 + 31535341 = 31535354
43 + 31535311 = 31535354
127 + 31535227 = 31535354
181 + 31535173 = 31535354
211 + 31535143 = 31535354
223 + 31535131 = 31535354
241 + 31535113 = 31535354
271 + 31535083 = 31535354

Showing the first eight; more decompositions exist.
