Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643206, here are decompositions:

  • 7 + 8643199 = 8643206
  • 73 + 8643133 = 8643206
  • 97 + 8643109 = 8643206
  • 193 + 8643013 = 8643206
  • 349 + 8642857 = 8643206
  • 367 + 8642839 = 8643206
  • 433 + 8642773 = 8643206
  • 673 + 8642533 = 8643206

Showing the first eight; more decompositions exist.
