Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738928, here are decompositions:

  • 47 + 8738881 = 8738928
  • 89 + 8738839 = 8738928
  • 127 + 8738801 = 8738928
  • 199 + 8738729 = 8738928
  • 257 + 8738671 = 8738928
  • 269 + 8738659 = 8738928
  • 337 + 8738591 = 8738928
  • 347 + 8738581 = 8738928

Showing the first eight; more decompositions exist.
