Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746280, here are decompositions:

  • 13 + 8746267 = 8746280
  • 19 + 8746261 = 8746280
  • 43 + 8746237 = 8746280
  • 73 + 8746207 = 8746280
  • 163 + 8746117 = 8746280
  • 211 + 8746069 = 8746280
  • 271 + 8746009 = 8746280
  • 463 + 8745817 = 8746280

Showing the first eight; more decompositions exist.
