Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675680, here are decompositions:

  • 3 + 8675677 = 8675680
  • 29 + 8675651 = 8675680
  • 59 + 8675621 = 8675680
  • 89 + 8675591 = 8675680
  • 107 + 8675573 = 8675680
  • 239 + 8675441 = 8675680
  • 281 + 8675399 = 8675680
  • 353 + 8675327 = 8675680

Showing the first eight; more decompositions exist.
