Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670272, here are decompositions:

  • 241 + 8670031 = 8670272
  • 283 + 8669989 = 8670272
  • 349 + 8669923 = 8670272
  • 379 + 8669893 = 8670272
  • 571 + 8669701 = 8670272
  • 601 + 8669671 = 8670272
  • 643 + 8669629 = 8670272
  • 661 + 8669611 = 8670272

Showing the first eight; more decompositions exist.
