Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534906, here are decompositions:

107 + 31534799 = 31534906
149 + 31534757 = 31534906
167 + 31534739 = 31534906
197 + 31534709 = 31534906
269 + 31534637 = 31534906
317 + 31534589 = 31534906
353 + 31534553 = 31534906
419 + 31534487 = 31534906

Showing the first eight; more decompositions exist.
