Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86478, here are decompositions:

  • 11 + 86467 = 86478
  • 17 + 86461 = 86478
  • 37 + 86441 = 86478
  • 79 + 86399 = 86478
  • 89 + 86389 = 86478
  • 97 + 86381 = 86478
  • 107 + 86371 = 86478
  • 109 + 86369 = 86478

Showing the first eight; more decompositions exist.
