Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747312, here are decompositions:

  • 61 + 8747251 = 8747312
  • 193 + 8747119 = 8747312
  • 229 + 8747083 = 8747312
  • 241 + 8747071 = 8747312
  • 271 + 8747041 = 8747312
  • 313 + 8746999 = 8747312
  • 349 + 8746963 = 8747312
  • 373 + 8746939 = 8747312

Showing the first eight; more decompositions exist.
