Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469820, here are decompositions:

  • 19 + 469801 = 469820
  • 67 + 469753 = 469820
  • 73 + 469747 = 469820
  • 97 + 469723 = 469820
  • 103 + 469717 = 469820
  • 163 + 469657 = 469820
  • 193 + 469627 = 469820
  • 277 + 469543 = 469820

Showing the first eight; more decompositions exist.
