Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628624, here are decompositions:

  • 23 + 8628601 = 8628624
  • 71 + 8628553 = 8628624
  • 73 + 8628551 = 8628624
  • 131 + 8628493 = 8628624
  • 181 + 8628443 = 8628624
  • 241 + 8628383 = 8628624
  • 271 + 8628353 = 8628624
  • 331 + 8628293 = 8628624

Showing the first eight; more decompositions exist.
