Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535376, here are decompositions:

  • 113 + 31535263 = 31535376
  • 149 + 31535227 = 31535376
  • 157 + 31535219 = 31535376
  • 163 + 31535213 = 31535376
  • 193 + 31535183 = 31535376
  • 233 + 31535143 = 31535376
  • 263 + 31535113 = 31535376
  • 269 + 31535107 = 31535376

Showing the first eight; more decompositions exist.
