Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644250, here are decompositions:

  • 7 + 8644243 = 8644250
  • 19 + 8644231 = 8644250
  • 37 + 8644213 = 8644250
  • 79 + 8644171 = 8644250
  • 103 + 8644147 = 8644250
  • 127 + 8644123 = 8644250
  • 193 + 8644057 = 8644250
  • 331 + 8643919 = 8644250

Showing the first eight; more decompositions exist.
