Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571376, here are decompositions:

  • 29 + 31571347 = 31571376
  • 43 + 31571333 = 31571376
  • 73 + 31571303 = 31571376
  • 157 + 31571219 = 31571376
  • 163 + 31571213 = 31571376
  • 227 + 31571149 = 31571376
  • 229 + 31571147 = 31571376
  • 233 + 31571143 = 31571376

Showing the first eight; more decompositions exist.
