Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647372, here are decompositions:

  • 3 + 8647369 = 8647372
  • 5 + 8647367 = 8647372
  • 23 + 8647349 = 8647372
  • 179 + 8647193 = 8647372
  • 191 + 8647181 = 8647372
  • 233 + 8647139 = 8647372
  • 281 + 8647091 = 8647372
  • 311 + 8647061 = 8647372

Showing the first eight; more decompositions exist.
