Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98800, here are decompositions:

  • 71 + 98729 = 98800
  • 83 + 98717 = 98800
  • 89 + 98711 = 98800
  • 131 + 98669 = 98800
  • 137 + 98663 = 98800
  • 173 + 98627 = 98800
  • 179 + 98621 = 98800
  • 227 + 98573 = 98800

Showing the first eight; more decompositions exist.
