Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662840, here are decompositions:

  • 29 + 8662811 = 8662840
  • 41 + 8662799 = 8662840
  • 71 + 8662769 = 8662840
  • 89 + 8662751 = 8662840
  • 191 + 8662649 = 8662840
  • 257 + 8662583 = 8662840
  • 353 + 8662487 = 8662840
  • 359 + 8662481 = 8662840

Showing the first eight; more decompositions exist.
