Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662780, here are decompositions:

  • 11 + 8662769 = 8662780
  • 29 + 8662751 = 8662780
  • 131 + 8662649 = 8662780
  • 197 + 8662583 = 8662780
  • 227 + 8662553 = 8662780
  • 239 + 8662541 = 8662780
  • 263 + 8662517 = 8662780
  • 293 + 8662487 = 8662780

Showing the first eight; more decompositions exist.
