Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78600, here are decompositions:

  • 7 + 78593 = 78600
  • 17 + 78583 = 78600
  • 23 + 78577 = 78600
  • 29 + 78571 = 78600
  • 31 + 78569 = 78600
  • 47 + 78553 = 78600
  • 59 + 78541 = 78600
  • 61 + 78539 = 78600

Showing the first eight; more decompositions exist.
