Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77000, here are decompositions:

  • 37 + 76963 = 77000
  • 127 + 76873 = 77000
  • 163 + 76837 = 77000
  • 181 + 76819 = 77000
  • 199 + 76801 = 77000
  • 223 + 76777 = 77000
  • 229 + 76771 = 77000
  • 283 + 76717 = 77000

Showing the first eight; more decompositions exist.
