Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646542, here are decompositions:

  • 13 + 8646529 = 8646542
  • 31 + 8646511 = 8646542
  • 139 + 8646403 = 8646542
  • 181 + 8646361 = 8646542
  • 283 + 8646259 = 8646542
  • 379 + 8646163 = 8646542
  • 439 + 8646103 = 8646542
  • 571 + 8645971 = 8646542

Showing the first eight; more decompositions exist.
