Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564552, here are decompositions:

  • 113 + 31564439 = 31564552
  • 191 + 31564361 = 31564552
  • 281 + 31564271 = 31564552
  • 311 + 31564241 = 31564552
  • 389 + 31564163 = 31564552
  • 419 + 31564133 = 31564552
  • 449 + 31564103 = 31564552
  • 563 + 31563989 = 31564552

Showing the first eight; more decompositions exist.
