Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77984, here are decompositions:

  • 7 + 77977 = 77984
  • 211 + 77773 = 77984
  • 223 + 77761 = 77984
  • 241 + 77743 = 77984
  • 271 + 77713 = 77984
  • 337 + 77647 = 77984
  • 367 + 77617 = 77984
  • 373 + 77611 = 77984

Showing the first eight; more decompositions exist.
