Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639328, here are decompositions:

  • 29 + 8639299 = 8639328
  • 37 + 8639291 = 8639328
  • 67 + 8639261 = 8639328
  • 79 + 8639249 = 8639328
  • 101 + 8639227 = 8639328
  • 109 + 8639219 = 8639328
  • 151 + 8639177 = 8639328
  • 157 + 8639171 = 8639328

Showing the first eight; more decompositions exist.
