Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644930, here are decompositions:

  • 3 + 8644927 = 8644930
  • 11 + 8644919 = 8644930
  • 17 + 8644913 = 8644930
  • 131 + 8644799 = 8644930
  • 149 + 8644781 = 8644930
  • 179 + 8644751 = 8644930
  • 227 + 8644703 = 8644930
  • 251 + 8644679 = 8644930

Showing the first eight; more decompositions exist.
