Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638914, here are decompositions:

  • 5 + 8638909 = 8638914
  • 23 + 8638891 = 8638914
  • 47 + 8638867 = 8638914
  • 61 + 8638853 = 8638914
  • 71 + 8638843 = 8638914
  • 107 + 8638807 = 8638914
  • 181 + 8638733 = 8638914
  • 223 + 8638691 = 8638914

Showing the first eight; more decompositions exist.
