Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582552, here are decompositions:

  • 5 + 31582547 = 31582552
  • 149 + 31582403 = 31582552
  • 233 + 31582319 = 31582552
  • 311 + 31582241 = 31582552
  • 359 + 31582193 = 31582552
  • 389 + 31582163 = 31582552
  • 431 + 31582121 = 31582552
  • 503 + 31582049 = 31582552

Showing the first eight; more decompositions exist.
