Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619436, here are decompositions:

  • 3 + 8619433 = 8619436
  • 5 + 8619431 = 8619436
  • 83 + 8619353 = 8619436
  • 167 + 8619269 = 8619436
  • 173 + 8619263 = 8619436
  • 239 + 8619197 = 8619436
  • 269 + 8619167 = 8619436
  • 359 + 8619077 = 8619436

Showing the first eight; more decompositions exist.
