Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690340, here are decompositions:

  • 7 + 8690333 = 8690340
  • 23 + 8690317 = 8690340
  • 37 + 8690303 = 8690340
  • 47 + 8690293 = 8690340
  • 73 + 8690267 = 8690340
  • 137 + 8690203 = 8690340
  • 149 + 8690191 = 8690340
  • 163 + 8690177 = 8690340

Showing the first eight; more decompositions exist.
