Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615400, here are decompositions:

  • 11 + 8615389 = 8615400
  • 23 + 8615377 = 8615400
  • 67 + 8615333 = 8615400
  • 113 + 8615287 = 8615400
  • 127 + 8615273 = 8615400
  • 139 + 8615261 = 8615400
  • 163 + 8615237 = 8615400
  • 181 + 8615219 = 8615400

Showing the first eight; more decompositions exist.
