Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002668, here are decompositions:

  • 151 + 1002517 = 1002668
  • 157 + 1002511 = 1002668
  • 181 + 1002487 = 1002668
  • 211 + 1002457 = 1002668
  • 241 + 1002427 = 1002668
  • 307 + 1002361 = 1002668
  • 379 + 1002289 = 1002668
  • 409 + 1002259 = 1002668

Showing the first eight; more decompositions exist.
