Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738432, here are decompositions:

  • 139 + 8738293 = 8738432
  • 151 + 8738281 = 8738432
  • 193 + 8738239 = 8738432
  • 223 + 8738209 = 8738432
  • 271 + 8738161 = 8738432
  • 331 + 8738101 = 8738432
  • 349 + 8738083 = 8738432
  • 379 + 8738053 = 8738432

Showing the first eight; more decompositions exist.
