Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720304, here are decompositions:

  • 23 + 8720281 = 8720304
  • 71 + 8720233 = 8720304
  • 113 + 8720191 = 8720304
  • 127 + 8720177 = 8720304
  • 167 + 8720137 = 8720304
  • 191 + 8720113 = 8720304
  • 193 + 8720111 = 8720304
  • 223 + 8720081 = 8720304

Showing the first eight; more decompositions exist.
