Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63888, here are decompositions:

  • 31 + 63857 = 63888
  • 47 + 63841 = 63888
  • 79 + 63809 = 63888
  • 89 + 63799 = 63888
  • 107 + 63781 = 63888
  • 127 + 63761 = 63888
  • 151 + 63737 = 63888
  • 179 + 63709 = 63888

Showing the first eight; more decompositions exist.
