Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656100, here are decompositions:

  • 3 + 8656097 = 8656100
  • 7 + 8656093 = 8656100
  • 31 + 8656069 = 8656100
  • 43 + 8656057 = 8656100
  • 67 + 8656033 = 8656100
  • 109 + 8655991 = 8656100
  • 163 + 8655937 = 8656100
  • 181 + 8655919 = 8656100

Showing the first eight; more decompositions exist.
