Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2456, here are decompositions:

  • 19 + 2437 = 2456
  • 67 + 2389 = 2456
  • 73 + 2383 = 2456
  • 79 + 2377 = 2456
  • 109 + 2347 = 2456
  • 163 + 2293 = 2456
  • 277 + 2179 = 2456
  • 313 + 2143 = 2456

Showing the first eight; more decompositions exist.
