Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636888, here are decompositions:

  • 19 + 8636869 = 8636888
  • 31 + 8636857 = 8636888
  • 97 + 8636791 = 8636888
  • 109 + 8636779 = 8636888
  • 151 + 8636737 = 8636888
  • 199 + 8636689 = 8636888
  • 241 + 8636647 = 8636888
  • 307 + 8636581 = 8636888

Showing the first eight; more decompositions exist.
