Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671584, here are decompositions:

  • 11 + 8671573 = 8671584
  • 67 + 8671517 = 8671584
  • 73 + 8671511 = 8671584
  • 83 + 8671501 = 8671584
  • 113 + 8671471 = 8671584
  • 127 + 8671457 = 8671584
  • 137 + 8671447 = 8671584
  • 157 + 8671427 = 8671584

Showing the first eight; more decompositions exist.
