Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526900, here are decompositions:

  • 7 + 31526893 = 31526900
  • 19 + 31526881 = 31526900
  • 37 + 31526863 = 31526900
  • 109 + 31526791 = 31526900
  • 127 + 31526773 = 31526900
  • 151 + 31526749 = 31526900
  • 211 + 31526689 = 31526900
  • 283 + 31526617 = 31526900

Showing the first eight; more decompositions exist.
