Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28350, here are decompositions:

  • 31 + 28319 = 28350
  • 41 + 28309 = 28350
  • 43 + 28307 = 28350
  • 53 + 28297 = 28350
  • 61 + 28289 = 28350
  • 67 + 28283 = 28350
  • 71 + 28279 = 28350
  • 73 + 28277 = 28350

Showing the first eight; more decompositions exist.
