Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638026, here are decompositions:

  • 53 + 8637973 = 8638026
  • 73 + 8637953 = 8638026
  • 83 + 8637943 = 8638026
  • 97 + 8637929 = 8638026
  • 157 + 8637869 = 8638026
  • 179 + 8637847 = 8638026
  • 197 + 8637829 = 8638026
  • 239 + 8637787 = 8638026

Showing the first eight; more decompositions exist.
