Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664842, here are decompositions:

  • 103 + 8664739 = 8664842
  • 181 + 8664661 = 8664842
  • 229 + 8664613 = 8664842
  • 283 + 8664559 = 8664842
  • 313 + 8664529 = 8664842
  • 409 + 8664433 = 8664842
  • 421 + 8664421 = 8664842
  • 619 + 8664223 = 8664842

Showing the first eight; more decompositions exist.
