Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666490, here are decompositions:

  • 11 + 8666479 = 8666490
  • 13 + 8666477 = 8666490
  • 31 + 8666459 = 8666490
  • 47 + 8666443 = 8666490
  • 59 + 8666431 = 8666490
  • 71 + 8666419 = 8666490
  • 73 + 8666417 = 8666490
  • 97 + 8666393 = 8666490

Showing the first eight; more decompositions exist.
