Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622500, here are decompositions:

  • 13 + 8622487 = 8622500
  • 31 + 8622469 = 8622500
  • 37 + 8622463 = 8622500
  • 79 + 8622421 = 8622500
  • 109 + 8622391 = 8622500
  • 127 + 8622373 = 8622500
  • 157 + 8622343 = 8622500
  • 163 + 8622337 = 8622500

Showing the first eight; more decompositions exist.
