Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720322, here are decompositions:

  • 5 + 8720317 = 8720322
  • 11 + 8720311 = 8720322
  • 41 + 8720281 = 8720322
  • 89 + 8720233 = 8720322
  • 131 + 8720191 = 8720322
  • 151 + 8720171 = 8720322
  • 211 + 8720111 = 8720322
  • 241 + 8720081 = 8720322

Showing the first eight; more decompositions exist.
