Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631984, here are decompositions:

  • 5 + 8631979 = 8631984
  • 7 + 8631977 = 8631984
  • 41 + 8631943 = 8631984
  • 73 + 8631911 = 8631984
  • 103 + 8631881 = 8631984
  • 181 + 8631803 = 8631984
  • 197 + 8631787 = 8631984
  • 241 + 8631743 = 8631984

Showing the first eight; more decompositions exist.
