Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621250, here are decompositions:

  • 7 + 8621243 = 8621250
  • 13 + 8621237 = 8621250
  • 37 + 8621213 = 8621250
  • 41 + 8621209 = 8621250
  • 61 + 8621189 = 8621250
  • 67 + 8621183 = 8621250
  • 97 + 8621153 = 8621250
  • 103 + 8621147 = 8621250

Showing the first eight; more decompositions exist.
