Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89888, here are decompositions:

  • 67 + 89821 = 89888
  • 79 + 89809 = 89888
  • 109 + 89779 = 89888
  • 199 + 89689 = 89888
  • 229 + 89659 = 89888
  • 277 + 89611 = 89888
  • 367 + 89521 = 89888
  • 397 + 89491 = 89888

Showing the first eight; more decompositions exist.
