Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999658, here are decompositions:

  • 5 + 999653 = 999658
  • 47 + 999611 = 999658
  • 59 + 999599 = 999658
  • 137 + 999521 = 999658
  • 167 + 999491 = 999658
  • 227 + 999431 = 999658
  • 269 + 999389 = 999658
  • 281 + 999377 = 999658

Showing the first eight; more decompositions exist.
