Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87564, here are decompositions:

  • 5 + 87559 = 87564
  • 7 + 87557 = 87564
  • 11 + 87553 = 87564
  • 17 + 87547 = 87564
  • 23 + 87541 = 87564
  • 41 + 87523 = 87564
  • 47 + 87517 = 87564
  • 53 + 87511 = 87564

Showing the first eight; more decompositions exist.
