Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731584, here are decompositions:

  • 5 + 8731579 = 8731584
  • 13 + 8731571 = 8731584
  • 53 + 8731531 = 8731584
  • 73 + 8731511 = 8731584
  • 83 + 8731501 = 8731584
  • 107 + 8731477 = 8731584
  • 137 + 8731447 = 8731584
  • 151 + 8731433 = 8731584

Showing the first eight; more decompositions exist.
