Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671868, here are decompositions:

  • 31 + 8671837 = 8671868
  • 157 + 8671711 = 8671868
  • 199 + 8671669 = 8671868
  • 229 + 8671639 = 8671868
  • 349 + 8671519 = 8671868
  • 367 + 8671501 = 8671868
  • 397 + 8671471 = 8671868
  • 421 + 8671447 = 8671868

Showing the first eight; more decompositions exist.
