Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679580, here are decompositions:

  • 23 + 8679557 = 8679580
  • 29 + 8679551 = 8679580
  • 53 + 8679527 = 8679580
  • 131 + 8679449 = 8679580
  • 227 + 8679353 = 8679580
  • 233 + 8679347 = 8679580
  • 269 + 8679311 = 8679580
  • 359 + 8679221 = 8679580

Showing the first eight; more decompositions exist.
