Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689940, here are decompositions:

  • 97 + 8689843 = 8689940
  • 163 + 8689777 = 8689940
  • 211 + 8689729 = 8689940
  • 229 + 8689711 = 8689940
  • 283 + 8689657 = 8689940
  • 313 + 8689627 = 8689940
  • 331 + 8689609 = 8689940
  • 349 + 8689591 = 8689940

Showing the first eight; more decompositions exist.
