Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22100, here are decompositions:

  • 7 + 22093 = 22100
  • 37 + 22063 = 22100
  • 61 + 22039 = 22100
  • 73 + 22027 = 22100
  • 97 + 22003 = 22100
  • 103 + 21997 = 22100
  • 109 + 21991 = 22100
  • 139 + 21961 = 22100

Showing the first eight; more decompositions exist.
