Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65478, here are decompositions:

  • 29 + 65449 = 65478
  • 31 + 65447 = 65478
  • 41 + 65437 = 65478
  • 59 + 65419 = 65478
  • 71 + 65407 = 65478
  • 97 + 65381 = 65478
  • 107 + 65371 = 65478
  • 151 + 65327 = 65478

Showing the first eight; more decompositions exist.
