Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720536, here are decompositions:

  • 3 + 8720533 = 8720536
  • 5 + 8720531 = 8720536
  • 23 + 8720513 = 8720536
  • 47 + 8720489 = 8720536
  • 53 + 8720483 = 8720536
  • 59 + 8720477 = 8720536
  • 89 + 8720447 = 8720536
  • 107 + 8720429 = 8720536

Showing the first eight; more decompositions exist.
