Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1178, here are decompositions:

  • 7 + 1171 = 1178
  • 61 + 1117 = 1178
  • 109 + 1069 = 1178
  • 127 + 1051 = 1178
  • 139 + 1039 = 1178
  • 157 + 1021 = 1178
  • 181 + 997 = 1178
  • 211 + 967 = 1178

Showing the first eight; more decompositions exist.
