Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998570, here are decompositions:

  • 19 + 998551 = 998570
  • 31 + 998539 = 998570
  • 43 + 998527 = 998570
  • 73 + 998497 = 998570
  • 127 + 998443 = 998570
  • 151 + 998419 = 998570
  • 193 + 998377 = 998570
  • 241 + 998329 = 998570

Showing the first eight; more decompositions exist.
