Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672888, here are decompositions:

  • 19 + 8672869 = 8672888
  • 67 + 8672821 = 8672888
  • 97 + 8672791 = 8672888
  • 109 + 8672779 = 8672888
  • 157 + 8672731 = 8672888
  • 181 + 8672707 = 8672888
  • 229 + 8672659 = 8672888
  • 241 + 8672647 = 8672888

Showing the first eight; more decompositions exist.
