Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639250, here are decompositions:

  • 23 + 8639227 = 8639250
  • 31 + 8639219 = 8639250
  • 43 + 8639207 = 8639250
  • 73 + 8639177 = 8639250
  • 79 + 8639171 = 8639250
  • 89 + 8639161 = 8639250
  • 97 + 8639153 = 8639250
  • 101 + 8639149 = 8639250

Showing the first eight; more decompositions exist.
