Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603824, here are decompositions:

  • 23 + 31603801 = 31603824
  • 67 + 31603757 = 31603824
  • 73 + 31603751 = 31603824
  • 103 + 31603721 = 31603824
  • 107 + 31603717 = 31603824
  • 113 + 31603711 = 31603824
  • 167 + 31603657 = 31603824
  • 181 + 31603643 = 31603824

Showing the first eight; more decompositions exist.
