Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535342, here are decompositions:

31 + 31535311 = 31535342
79 + 31535263 = 31535342
109 + 31535233 = 31535342
199 + 31535143 = 31535342
211 + 31535131 = 31535342
229 + 31535113 = 31535342
283 + 31535059 = 31535342
331 + 31535011 = 31535342

Showing the first eight; more decompositions exist.
