Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664474, here are decompositions:

  • 23 + 8664451 = 8664474
  • 41 + 8664433 = 8664474
  • 43 + 8664431 = 8664474
  • 47 + 8664427 = 8664474
  • 53 + 8664421 = 8664474
  • 61 + 8664413 = 8664474
  • 97 + 8664377 = 8664474
  • 107 + 8664367 = 8664474

Showing the first eight; more decompositions exist.
