Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664456, here are decompositions:

  • 5 + 8664451 = 8664456
  • 23 + 8664433 = 8664456
  • 29 + 8664427 = 8664456
  • 37 + 8664419 = 8664456
  • 43 + 8664413 = 8664456
  • 67 + 8664389 = 8664456
  • 79 + 8664377 = 8664456
  • 89 + 8664367 = 8664456

Showing the first eight; more decompositions exist.
