Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535294, here are decompositions:

31 + 31535263 = 31535294
61 + 31535233 = 31535294
67 + 31535227 = 31535294
151 + 31535143 = 31535294
163 + 31535131 = 31535294
181 + 31535113 = 31535294
211 + 31535083 = 31535294
283 + 31535011 = 31535294

Showing the first eight; more decompositions exist.
