Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9100, here are decompositions:

  • 41 + 9059 = 9100
  • 59 + 9041 = 9100
  • 71 + 9029 = 9100
  • 89 + 9011 = 9100
  • 101 + 8999 = 9100
  • 131 + 8969 = 9100
  • 137 + 8963 = 9100
  • 149 + 8951 = 9100

Showing the first eight; more decompositions exist.
