Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1104, here are decompositions:

  • 7 + 1097 = 1104
  • 11 + 1093 = 1104
  • 13 + 1091 = 1104
  • 17 + 1087 = 1104
  • 41 + 1063 = 1104
  • 43 + 1061 = 1104
  • 53 + 1051 = 1104
  • 71 + 1033 = 1104

Showing the first eight; more decompositions exist.
