Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683220, here are decompositions:

  • 3 + 8683217 = 8683220
  • 19 + 8683201 = 8683220
  • 31 + 8683189 = 8683220
  • 37 + 8683183 = 8683220
  • 61 + 8683159 = 8683220
  • 67 + 8683153 = 8683220
  • 157 + 8683063 = 8683220
  • 193 + 8683027 = 8683220

Showing the first eight; more decompositions exist.
