Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720036, here are decompositions:

  • 37 + 8719999 = 8720036
  • 97 + 8719939 = 8720036
  • 163 + 8719873 = 8720036
  • 223 + 8719813 = 8720036
  • 337 + 8719699 = 8720036
  • 373 + 8719663 = 8720036
  • 433 + 8719603 = 8720036
  • 463 + 8719573 = 8720036

Showing the first eight; more decompositions exist.
