Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739680, here are decompositions:

  • 7 + 8739673 = 8739680
  • 13 + 8739667 = 8739680
  • 43 + 8739637 = 8739680
  • 73 + 8739607 = 8739680
  • 97 + 8739583 = 8739680
  • 151 + 8739529 = 8739680
  • 181 + 8739499 = 8739680
  • 199 + 8739481 = 8739680

Showing the first eight; more decompositions exist.
