Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690928, here are decompositions:

  • 7 + 8690921 = 8690928
  • 11 + 8690917 = 8690928
  • 61 + 8690867 = 8690928
  • 101 + 8690827 = 8690928
  • 107 + 8690821 = 8690928
  • 131 + 8690797 = 8690928
  • 139 + 8690789 = 8690928
  • 251 + 8690677 = 8690928

Showing the first eight; more decompositions exist.
