Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20846, here are decompositions:

  • 37 + 20809 = 20846
  • 73 + 20773 = 20846
  • 97 + 20749 = 20846
  • 103 + 20743 = 20846
  • 127 + 20719 = 20846
  • 139 + 20707 = 20846
  • 283 + 20563 = 20846
  • 313 + 20533 = 20846

Showing the first eight; more decompositions exist.
