Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1110, here are decompositions:

  • 7 + 1103 = 1110
  • 13 + 1097 = 1110
  • 17 + 1093 = 1110
  • 19 + 1091 = 1110
  • 23 + 1087 = 1110
  • 41 + 1069 = 1110
  • 47 + 1063 = 1110
  • 59 + 1051 = 1110

Showing the first eight; more decompositions exist.
