Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1124, here are decompositions:

  • 7 + 1117 = 1124
  • 31 + 1093 = 1124
  • 37 + 1087 = 1124
  • 61 + 1063 = 1124
  • 73 + 1051 = 1124
  • 103 + 1021 = 1124
  • 127 + 997 = 1124
  • 157 + 967 = 1124

Showing the first eight; more decompositions exist.
