Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998240, here are decompositions:

  • 3 + 998237 = 998240
  • 43 + 998197 = 998240
  • 73 + 998167 = 998240
  • 79 + 998161 = 998240
  • 157 + 998083 = 998240
  • 163 + 998077 = 998240
  • 211 + 998029 = 998240
  • 223 + 998017 = 998240

Showing the first eight; more decompositions exist.
