Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732400, here are decompositions:

  • 29 + 8732371 = 8732400
  • 31 + 8732369 = 8732400
  • 37 + 8732363 = 8732400
  • 101 + 8732299 = 8732400
  • 109 + 8732291 = 8732400
  • 139 + 8732261 = 8732400
  • 191 + 8732209 = 8732400
  • 199 + 8732201 = 8732400

Showing the first eight; more decompositions exist.
