Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725880, here are decompositions:

  • 3 + 8725877 = 8725880
  • 67 + 8725813 = 8725880
  • 181 + 8725699 = 8725880
  • 199 + 8725681 = 8725880
  • 211 + 8725669 = 8725880
  • 223 + 8725657 = 8725880
  • 271 + 8725609 = 8725880
  • 313 + 8725567 = 8725880

Showing the first eight; more decompositions exist.
