Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640102, here are decompositions:

  • 43 + 8640059 = 8640102
  • 89 + 8640013 = 8640102
  • 101 + 8640001 = 8640102
  • 151 + 8639951 = 8640102
  • 179 + 8639923 = 8640102
  • 181 + 8639921 = 8640102
  • 193 + 8639909 = 8640102
  • 199 + 8639903 = 8640102

Showing the first eight; more decompositions exist.
