Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747090, here are decompositions:

  • 7 + 8747083 = 8747090
  • 19 + 8747071 = 8747090
  • 127 + 8746963 = 8747090
  • 151 + 8746939 = 8747090
  • 211 + 8746879 = 8747090
  • 229 + 8746861 = 8747090
  • 241 + 8746849 = 8747090
  • 271 + 8746819 = 8747090

Showing the first eight; more decompositions exist.
