Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620880, here are decompositions:

  • 7 + 8620873 = 8620880
  • 19 + 8620861 = 8620880
  • 157 + 8620723 = 8620880
  • 193 + 8620687 = 8620880
  • 241 + 8620639 = 8620880
  • 277 + 8620603 = 8620880
  • 313 + 8620567 = 8620880
  • 337 + 8620543 = 8620880

Showing the first eight; more decompositions exist.
