Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535474, here are decompositions:

7 + 31535467 = 31535474
97 + 31535377 = 31535474
163 + 31535311 = 31535474
211 + 31535263 = 31535474
241 + 31535233 = 31535474
331 + 31535143 = 31535474
367 + 31535107 = 31535474
463 + 31535011 = 31535474

Showing the first eight; more decompositions exist.
