Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526822, here are decompositions:

  • 3 + 31526819 = 31526822
  • 13 + 31526809 = 31526822
  • 31 + 31526791 = 31526822
  • 73 + 31526749 = 31526822
  • 109 + 31526713 = 31526822
  • 433 + 31526389 = 31526822
  • 463 + 31526359 = 31526822
  • 541 + 31526281 = 31526822

Showing the first eight; more decompositions exist.
