Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84478, here are decompositions:

  • 11 + 84467 = 84478
  • 29 + 84449 = 84478
  • 41 + 84437 = 84478
  • 47 + 84431 = 84478
  • 71 + 84407 = 84478
  • 89 + 84389 = 84478
  • 101 + 84377 = 84478
  • 131 + 84347 = 84478

Showing the first eight; more decompositions exist.
