Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544760, here are decompositions:

  • 11 + 31544749 = 31544760
  • 41 + 31544719 = 31544760
  • 43 + 31544717 = 31544760
  • 47 + 31544713 = 31544760
  • 103 + 31544657 = 31544760
  • 173 + 31544587 = 31544760
  • 199 + 31544561 = 31544760
  • 227 + 31544533 = 31544760

Showing the first eight; more decompositions exist.
