Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664816, here are decompositions:

  • 29 + 8664787 = 8664816
  • 59 + 8664757 = 8664816
  • 73 + 8664743 = 8664816
  • 257 + 8664559 = 8664816
  • 263 + 8664553 = 8664816
  • 269 + 8664547 = 8664816
  • 383 + 8664433 = 8664816
  • 389 + 8664427 = 8664816

Showing the first eight; more decompositions exist.
