Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599928, here are decompositions:

  • 11 + 31599917 = 31599928
  • 167 + 31599761 = 31599928
  • 257 + 31599671 = 31599928
  • 317 + 31599611 = 31599928
  • 587 + 31599341 = 31599928
  • 827 + 31599101 = 31599928
  • 1019 + 31598909 = 31599928
  • 1061 + 31598867 = 31599928

Showing the first eight; more decompositions exist.
